Wiring The Power; Output Wiring; Wiring To A Motorized Valve; Wiring To A Boiler - heat-timer MPC Platinum Installation And Operation Manual

WIRING THE POWER

• If possible, provide a dedicated circuit breaker for the MPC Platinum. DO NOT connect
the MPC Platinum to a circuit breaker connected to high inductance devices such as
relays, pumps, fans, or motors.
• Bring the 120VAC 60Hz power wires through a bottom knockout (KO) of the enclosure.
• Class 1 voltages must enter the enclosure through a different knockout from any Class 2
voltage wiring.
• Connect the hot line to terminal marked LINE.
• Connect the neutral line to the terminal marked NEUT. DO NOT share neutrals. The
neutral line MUST come directly from the circuit breaker.
• Connect the green ground screw to earth ground. DO NOT use the neutral line as a
ground.
• Heat-Timer recommends the installation of a Surge Suppressor and a Power Switch
before the Power Line connection for safety and ease of service.

OUTPUT WIRING

• All of the MPC Platinum's outputs DO NOT SOURCE any power. If power is needed at
a specific output, a separate power source must be wired in series with the output.
• Each of the output relays can switch a 6A resistive at 120VAC load or a 1A inductive
load.

WIRING TO A MOTORIzED VALVE

• The MPC Platinum is capable of operating a boiler, a floating motorized valve, or both.
• The MPC Platinum output terminal R (5) is the Common. Wire it to the 24 VAC power
source (transformer).
• Connect the transformer's second wire to the actuator Common terminal.
• The MPC Platinum output terminal B (4) is the Normally Open (N.O.). Wire it to the
actuator Open terminal.
• The MPC Platinum output terminal W (6) is the Normally Closed (N.O.). Wire it to the
actuator Close terminal.
• The N.O. and N.C. contacts are dry contacts only. They do not source any power. The
transformer is the actuator power source.
outages activates the Output and System

WIRING TO A BOILER

• The MPC Platinum s designed to operate a boiler, a floating motorized valve, or both.
• The BURNER output terminals are 7 and 8. They do not source any power. Wire the
burner output in series with the boiler limit circuit.
