MVSRLY01 Wiring Instructions
12 AMP pump relay (MVSRLY01) is DPDT. Connect 120V supply to terminal 1 and 4. Connect pump to terminal 3 and 6. Use 12/2 w/ground (min.) for 120V line voltage wiring. Pump must also be grounded.
Low voltage coil terminals (24V) can be wired for either a HRVC541 Zone Valve
Controller or a simple thermostat control circuit.
HRVC541 Zone Valve Controller wiring. Connect 24V H+ IN to V1 controller terminal and 24V N- IN to V2 controller terminal, 36” 18/2 connector included with MVSRLY01.
Thermostat Control Circuit wiring. Connect 24V N- IN directly to transformer N-. Connect 24V H+ IN to thermostat (control switch), then connect thermostat to transformer 24V H+). Thermostat breaks (or connects) the control voltage (24V) HOT (+) to the relay.
All wiring must comply with the
NEC and local electrical codes, if applicable.
All wiring must be preformed by a licensed electrician.
