HEVAC HTC-4 2-Stage Temperature Controller

The HTC-4 Temperature Controller is primarily designed for the control of 2 Stage Heat and 2 Stage Cool Air-conditioning units. All output relays are voltage free permitting use on either 240 Volt or 24 Volt circuitry. Stage switch on points are individually adjustable with their ON/OFF status displayed via LED indicators. The HTC-4 Temperature Controller is ideally suited for DIN rail mounting in a switchboard or directly inside the A/C unit if required.
