RC840T Installation Guide On/Off Switching Electric Heating Relay with Built-in 24 V Transformer ■ Application 1. The RC840T Electric Heating Relay is designed to control a line voltage resistive load from a low voltage thermostat. The RC840T relay has a built-in 24 V transformer and is compatible with 3-wire (R,C,W) thermostats as well as 2-wire mechanical and battery operated thermostats. The RC840T operates silently and can be installed in bedrooms, living rooms, or any other occupied area without disturbing occupants. On a call for heat, the relay is immediately activated; there is no delay. This increases temperature control and comfort. NOTE: Not recommended for fast-cycling modulated regulation. For fast-cycling heating equipment, It is recommended to use the RT850 or RT850T (integrated 24 V transformer) Solid State Relay. I 🞐 Once mounting and wiring have been completed, return power to the heating system and test the installation. ❑ Increase the thermostat temperature to activate the relay. Allow system operation long enough to proof installation. Once installation has been proofed, set temperature to normal setpoint. 🞐 Typical Wiring Diagrams 3. Load □ Installation 2. The RC840T must be installed in an area where the temperature is between -4°F and 140°F (-20°C and 60°C). The RC840T can be installed on the side of an electrical box or a distribution panel or inside the wiring compartment of an electric baseboard. Low-voltage 2-wire thermostat Junction box Red Black Blue For proper installation, use a screw and a washer. You must provide an overload protection and disconnect as required.

Installation should be carried out by an electrician. Disconnect power supply before installing the relay to prevent electrical shock. ■ Secure relay to the mounting surface using the two mounting brackets. Use the supplied lock nut to secure the relay to the junction box. □ Wire the relay and connect according to typical wiring diagrams (refer to figures 1 & 2). You must provide an overload protection and disconnect as required. Figure 2 : Connection to a 3-wire low voltage thermostat RC840T 400-276-002-C 17/1/07 1/2 ❑ Electrical Specifications 4.
