Differential Temperature Controller T2 T1

T1 air temperature t2 evaporator temperature tim time based control.

Differential temperature controller t2 t1.

It is possible limit the maximum temperature of the storage tank and also activate a freeze protection function. When the temperature reaches the differential set value t2 t1 it automatically runs the circulation pump until the two temperature zones reach equilibrium according to your setting the s relay can be used to control electric heating when the solar heating has failed to reach the set temperature. When the temperature reaches the differential set value t2 t1 it automatically runs the circulation pump until the two temperature zones reach equilibrium according to your setting the second relay can be used to control electric heating when the solar heating has failed to reach the set temperature. Dtc at adjustable differential from 5 to 32f and max shut down or over temp warning shut down for storage tank adjustable from 80 to 200f.

Fans remain on when the compressor is on. Tmp temperature based control. Solar powered differential temperature controllers. The fans are turned on again with the fdh differential.

The controller reads the temperatures of the storage tank t1 and of the collector t2 when this differential temperature t2 t1 is higher than a set value dt it will switch on the water pump. Fixed differential is less than 1 degree f. When the compressor is off the fans remain on as long as the temperature difference t2 t1 is greater than fdt. It controls the water circulation system based on the difference of temperature between the solar collector and the storage tank or swimming pool the instrument contains two ntc type temperature sensors and a control output for activating the water circulation pump.
