Description

Relay isolation for Omnistat2 thermostats. This optional module may be needed for HVAC systems using non-standard voltages. Mounting clips and instructions are included. For use when continuous 24-volt power is not available from the HVAC equipment. It completely isolates an RC-80B series (Rc-8x) thermostat from the heating and cooling system and allows a separate 24-volt AC transformer (sold separately) to power the thermostat. This is necessary because the Omnistat2 receives power from the HVAC unit. If there are separate heat and cool units, this product allows you to only obtain power from one but control both.
