Optimised Heating Function
The controller is monitoring the secondary return temperature and as the temperature in the area surrounding the room thermostat nears the set point, the controller will then start to lower the secondary flow setpoint temperature. This function is aimed at UFH situations where temperature over-shoot in rooms is a particular problem.
Pump protection - to prevent pump ‘seizing’ during long shut down periods in the summer months. A timed programme is available to run the pump at regular intervals. The periods can be adjusted at time of commissioning if desired.
Power Loss Shut down - the controller retains enough residual power to shut down the control valve on loss of power to prevent wasted heat and prevent possibility of scalding with uncontrolled high DHW temperatures.
Shut down if control is lost due to failure of the control valve for high temperature safety.
Pressure Independent Control valve
PICV cartridge is built into the inlet block. Fast acting stepper motor, dual speed PID control allows one application valve. DPCV can be employed externally if required where differential pressures exceed 4kPa. Combines an externally adjustable automatic balancing valve, a differential pressure control valve and a full authority modulating control valve.
Filling Group with removable pipe
Wras approved and with double check valve for back flow protection.
Keep warm function
Temperature controlled to maintain heat within the DHW plate heat exchanger. Function starts at a pre-set time of non-use which is programmable between 5 minutes and 24 hours, the function also has an ON or OFF setting.
