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.
Differential temperature controller solar.
The following differential temperature controllers offer maximum operating efficiency and flexibility to effectively manage today s innovative thermal energy systems our products are designed to operate a wide range of thermal applications such as swimming pool heating domestic water heating multiple application intergration and sophisticated space heating and cooling.
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.
These controllers are perfect for solar hot water and solar air heating and industrial thermostat controls.
Ae2 temperature controller has two programmable outputs for controlling pumps fans and humidity control devices upto 8 amps each relay.
The second relay can be used to control electric heating when the solar heating has failed to reach the set temperature.
