The HTC-5 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 V or 24 Volt circuitry. Stage switch on points are adjustable with
their ON/OFF status displayed via LED indicators. The HTC-5 also incorporates a random time delay on the fan relay output enabling
multiple A/C Unit startups using only one Time Clock or System Start Switch.
