Two-circuit heating unit ST-517 from Tech, suitable for cooperation with two circulation pumps. This unit is activated by a signal from the room thermostat regarding the space's underheating, adjusting the appropriate pump.
The ST-517 can also be used in underfloor installation, requiring an additional bimetallic sensor for temperature control. In case of temperature exceeding the limit, it disconnects the pump to prevent overheating.
The controller works with two room thermostats, ensuring the effective operation of the heating system. The wiring connection must be performed by a specialized person to avoid damage.
