THE IPEX MANUAL OF THE IPEX MANUAL OF MODERN HYDRONICS The IPEX WarmRite Control Panel product line was developed using this process, in combination with valuable feedback from the North American market place. The result is the following eleven different Control Panels (CP) Injection Mixing CP Recirculating Zone CP Recirculating Zone CP with Expansion Tank CP with Heat Exchanger Floor Warming CP Multi Zone Manifold Station Manifold Station with Circulator Manifold Station Snowmelt / Industrial CP Injection Mixing Secondary CP Isolation Module Each control panel is described in this section. However, because the panels have numerous common elements, a review of their similarities is in order. For detailed information, application notes and installation / operation manuals are available for each panel. 7-1.3 Operating Principles All panels are designed to control the average floor temperature required to compensate for ongoing heat loss. Each panel does this by cycling between heat input (on cycle) and no heat input (off cycle). During the on cycle, additional heat is added to the pipe loops to bring the floor temperature to its desired level.
The ratio between the on and off cycle is proportional to the average heat needed in the floor. Simply put, if it is warm outside the heat loss is low. The on cycle is short and the off cycle is long. If the opposite is true and it is cold outside, the heat loss will be high causing the on cycle to be long and the off cycle to be short. In principle, radiant floor systems are designed so that on the coldest day of the year, the on cycle will operate 100% of the time.

7-1.4 Supply Water Temperature Most panels operate on constant supply temperature. Only the Injection Mixing Control Panel modulateschanges continuously-the supply temperature based on outdoor reset. The Control Panel with Heat Exchanger and the Floor Warming Control Panel have a built-in tempering valve to set the supply temperature. These three panels control the floor supply temperature so no external supply water temperature control is needed. All other panels rely on receiving the calculated design water temperature. 7-1.5 Space Temperature Control Most of the panels are primarily operated as a zone control mechanism.
They can provide loop control if necessary, but one should always consider the way the building is used and clarify if zone control is appropriate, or if loop by loop control is needed. Loop by loop control always requires more hardware components than zone control. Designers should consider how the building is used. Who is using it What comfort level is required How even and constant is the required indoor temperature What level of accuracy is required from the control system One must first identify what is really required and design accordingly.
7-1.6 Why zone control It is fair to say that the most fundamental requirement of every heating system is to provide constant temperature in the heated space. There are exceptions of course, but mostly a set temperature is desired throughout the heating season. The opposite of this occurs if a building needs to be heated only for a short time, then cooled and heated again.

We have a warmrite floor kitec radiant system in our house. I was shown a few years ago to take off the CSI cap at the - Answered by a verified HVAC Technician.
In most cases, high mass radiant floor may not be the best option for this type of heating pattern. Where radiant heating thrives is in constant temperature environments. This being the case, the fundamental requirement is to be able to set a desired temperature and allow the system to maintain it - this is what zone control does best. To clarify, zone control means that all pipe loops (or heat emitters) connected to a manifold are controlled by one thermostat or sensor. However, this does not mean that the temperature must be the same in all areas covered by the loops from a single manifold. Different temperatures can be set within the zone by adjusting the balancing valve on each loop. Adjusting the flow rate loop results in different temperatures in the areas covered by the loops.
Warmrite Return Manifold Manual
7-1.7 Setting the Temperature All panels have a balancing valve for each pipe loop fitted on the return manifold. Most panels also have flow rate indicators on the return manifold. The desired temperature relationship can be set easily and with no additional hardware-i.e. A thermostat in every room and an actuator on every loop.
This approach to temperature control works very well as long as the preference 74 SECTION 7 PRE-ASSEMBLED CONTROL PANELS is for a consistent temperature pattern which is not often altered. The temperature difference between the areas will remain the same unless the balancing valves are readjusted. Naturally there are applications when the temperature setting has to be changed more frequently - such as a motel where guests change every day, and with them so do individual comfort requirements. Perhaps in our own home there is a guest bedroom that is only used sporadically. In these cases, separate thermostats are required. The pipe loops serving these spaces will have valve actuators connected to the appropriate room thermostat. When the room is occupied and that thermostat calls for heat, valves open on those loops until the appropriate setting is satisfied.
The provision for individual loop valves is available on all WarmRite Floor control panels designed for residential or office environments. Industrial and Secondary Injection Mixing Control Panels differ from the others in that the environments they are designed for rarely require loop by loop control. In large areas, the flow adjustment in a single loop has virtually no effect on the overall heat output. There are no sophisticated balancing or actuated valves in these panels because they are not required. All of the other control panels have been designed to accommodate individual loop by loop control when required. Every panel designed for closed loop systems has an automatic air vent on the supply manifold and a fill/drain valve on both manifolds. Each is equipped with a pressure gauge on the return manifold and two temperature gauges: one for supply and one for return water temperature.
The temperature drop in the system characterizes best how the unit is operating. 7-1.8 Protection from Overheating All panels - except the manifold station - are fitted with a limit thermostat to protect the floor from overheating. Floor surface temperature should be less than 85 deg. For human comfort. The limit thermostat monitors the supply water temperature which is proportional to the floor surface temperature. If the supply temperature reaches the setpoint, the limit thermostat turns off the heat input.
This is a factory setting based on typical concrete slab installations. When higher supply temperatures are required, it can be readjusted accordingly. See the Application Notes and Installation / Operation Manual supplied with each panel for more details.
No Heat The wall thermostat controls line voltage to the zone valves in a hot water system and the current flowing through the embedded heating cables with an electric system. Begin your troubleshooting by making sure there is voltage present at the thermostat using a noncontact voltage tester. If there is no voltage present, you have a tripped circuit breaker or blown fuse in the service panel. Reset the breaker or replace the blown fuse and recheck for power. If there was power at the thermostat, check for voltage at the zone valve in the case of a water system, or the splice box in the case of an electrical system, using the noncontact voltage tester.

No voltage at those points indicates a bad thermostat. To replace a thermostat or any other component in the heating system, first turn off the circuit breaker.
Remover the cover from the thermostat, disconnect the wiring by loosening the terminal screws and slipping the wires out from under them. Remove the old thermostat from the wall and take it with you to get an exact replacement. Replacing a Defective Zone Valve Turn off the circuit breaker and then disconnect the wires coming from the thermostat by loosening the terminals screws and slipping the wires out from under them. Turn off the hot water supply to the zone valve and open the system drain valve to drain as much water as possible from the heating coil. Then, unsolder the old valve from between the copper pipe supplying the hot water and the pipe leading to the heating coil. Take the old valve with you to the home center to get an exact replacement. Solder the replacement valve in place, connect the wiring and turn on the water and check for leaks.
Replacing a Defective Heating Cable or Mat Heating cables or mats may be located on the underside of the rough flooring or sandwiched between the subfloor and the finished flooring. In the former case, replacing them is relatively easy, just a matter of removing the fiberglass bat insulation and then the defective cable or heating mat section. In the latter type of installation, you will have to remove the finish floor from over it to access it. This, depending on the type of finish floor you have, can be quite challenging. In most cases, you will not be able to reuse the flooring you remove. Once you have gained access to the heating cable or mat, you can determine which section is defective by taking continuity readings through each section with a digital multimeter set on its Ohms range. Again, take the old section of cable or mat with you to get an exact replacement.
Room Does Not Get Warm Enough In a room that doesn't heat up satisfactorily, you may have a thermostat that is opening too soon, a zone valve that is not opening up fully or one or more defective sections of heating cable or mats if there are a number of sections connected in parallel. To determine if the thermostat is the problem, simply bypass the thermostat with a set of jumper wires.

Most zone valves can be disassembled and cleaned if they are not opening up all the way. In the case of a defective section of parallel-connected heating cables, separate the sections from one another and check the continuity through each section.
