Under floor Heating Controller Circuit Diagram
Central heating systems that include under- floor heating of ten leave the extra pump used to pump the water through the under-floor pipes running continuously. The reason for this is that the central heating controller doesn’t have a separate control circuit and output for the under floor heating pump. Under-floor Heating Controller Circuit Diagram This circuit was designed to control the under- floor heating pump independently or via the switch in the living room thermostat. The design has been made very flexible and can be connected in four different ways: Temperature sensor 1 is connected to the inlet pipe of the under floor heating , Temperature sensor 2 is shor ted. The pump is turned on when the inlet pipe becomes warm enough. When the temperature of the inlet pipe drops below the trigger temperature the pump will continue to run for 20 minutes. Temperature sensor 1 is connected to the inlet pipe of the under floor heating , Temperature sensor 2 is connected to the outlet pip...
