Detailed Product Description

Operation

The controller (18) will switch on the pump when the temperature at the collector sensor TC is higher than the return temperature TR by at least the pre selected (delta T) amount.
The pump circulates a heat transfer liquid around the loop.
Heat from the collector is transferred to the domestic water through the heat exchange coil in the tank.
With the pump running, if delta T is not met, the pump will switch odd.

When a present tank temperature is reached at Tmax, the controller switches off the pump.
The check valve (non-return valve) prevents heat from the tank fixing towards the collectors should the tank be warmer (e.g. at night)
