The Comfort Control Relay Panel (CCRP) can control up to nine direct connected electrical circuits. In a special ordered factory configuration, it can also provide peak control for fluid regulated ETS systems (i.e. Steffes "S" series room heaters and most European models). When the CCRP receives the power company control signal, the relays will respond by controlling the devices wired into them. The panel controls fluid regulated ETS systems by sending voltage pulses to the heater's charge control regulating system at varying rates based on outdoor temperature and the power company's peak control status.
If the PLC transmitter in the relay panel is utilized, peak control signals are sent through the power lines serving the installation to remote devices. The Steffes 1000, 2000, and 2100 series room heating units, Comfort Plus systems, and other controllable devices incorporating the Steffes PLC Receiver that are served power by the same power company distribution transformer will respond to this signal. The PLC feature frees up the relays for control of other direct wired devices.
The CCRP is capable of providing automatic brick core charging with the addition of an outdoor temperature sensor for the 1000, 2000, and/or 2100 series ETS room heating units as well as Comfort Plus systems and fluid regulated ETS room heating systems (i.e., Steffes "S" series room heaters and most European models).
The CCRP's built in transmitter can send the outdoor temperature information through the existing power lines. Any 1000, 2000, and/or 2100 series heaters as well as Comfort Plus systems on the same power company distribution transformer as the CCRP will receive this information and store heat in their bricks in relation to the outside temperatures.
If the CCRP is to be utilized for automatic charge control of fluid regulated ETS heaters, it must be special ordered from the factory with this feature. Panels with this option use outdoor temperature information to provide voltage pulses to the heater's charge control regulating system. The rate of the voltage pulses signal the amount of heat that the heater(s) should be storing in relation to the outside temperatures. The CCRP can provide automatic charge control for up to 10 heaters using this feature in its standard configuration. With a special modification, more than 10 heaters can be controlled.
The PLC transmitter built into the CCRP is capable of providing room temperature set back information, with the use of a signaling device, through the existing power lines. Any 1000, 2000 and 2100 series room heating units on the same power company distribution transformer as the CCRP will receive this information and respond accordingly.
Multiple Rate Strategy Control Signals: The CCRP is capable of accepting up to six (6) separate power company control signals. This feature works well in areas using multiple rate strategies in the same application.
The peak override module is an optional feature that allows the use of normally controlled devices, such as a water heater, during a peak control time. It allows up to 6 circuits to be overridden in 60-minute intervals. This feature is great for areas using Time-Of-Use metering and control strategies.
