! "" # RC845 The RC845 is designed to control either a gas, oil furnace burner or an electric furnace as well as the fan when adding a heat pump on an existing heating system. The RC845 includes a low voltage dry contact output to activate the auxiliary heating system, and a line voltage contact output to control the fan operation. When installed with an Aube heat pump thermostat (TH144HP), the installer can configure the auxiliary heat sequence to turn OFF the compressor (Y) on a call for auxiliary heat. The RC845 combined with the TH144HP thermostat offers a complete integrated solution that simplifies installation and provides proper equipment operation. • RC845 red wire must be connected to the fan side. 🞐 Connect the RC845 low voltage terminals W, G and C to the corresponding terminals on the heat pump thermostat. ❑ Connect the RC845 Auxiliary Heat dry contact outputs (T, T) to: • oil burner terminals T and T; or • gas control terminals TH and TH; or • electric heat furnace terminals R and W. ❒ Once mounting and wiring have been completed, return power to the heating system and proof installation. ⬧ To proof installation, select the Emergency Heat mode on your thermostat. Increase the thermostat setpoint to activate the auxiliary heating system. Allow system operation long enough to proof relay operation. Once installation has been proofed, disable the Emergency Heat mode and define setpoint for normal operation. All wiring must comply with national and local electrical code regulations. Installation should be carried out by an electrician. Disconnect power supply before installing the relay to prevent electrical shock. ■ Secure relay in or on the electrical enclosure using the provided lock-nut (see Figure 1). □ Wire the RC845 line voltage side as per Figure 2. The line voltage contact must be connected in parallel with the Plenum Thermostat, usually known as the Fan and Limit Controller (fan side). Connect as follows: • RC845 black wire must be connected to L1 (hot). On a call for heat or cool, the heat pump thermostat (TH144HP) activates the G terminal; the RC845 activates the fan. When auxiliary heat is required, the heat pump thermostat activates the W terminal; the RC845 dry contact outputs T, T closes to activate the auxiliary heat system. NOTE: The RC845 line voltage contact is connected in parallel with the furnace fan and limit controller (fan side). When the thermostat setpoint has been reached, the fan may continue to run until the fan and limit controller setpoint is reached.
