WARNING
Electrical Shock Hazard.
Can cause serious injury, death or property
damage.
Disconnect power supply before beginning wiring to
prevent electrical shock and equipment damage. More
than one disconnect may be involved.
Ground Connection
The ground connection on the controller must not be used as
a central ground connection for the 120 Vac connections.
1. Use the common ground terminal next to the controller,
close to connector J4–12.
2. Connect the central ground terminal with the connection
contact of the controller.
3. Connect the ground wire of the main power connector,
any pumps, and the ignition wire to the central ground
terminal.

Electrical Connections
24 V Power
1. 24 Vac – J8–1.
2. 24 Vac Return – J8–2.
3. STAT 24V input – J4–10.
Pumps A, B, C Power Line(s)
1. L1 (Hot) in to control J4-3, 5, 7.
2. L1 (Hot) out to Pumps J4-2, 4, 6.
3. Ground to central ground terminal, not to Ground on
J4–12.
Low Voltage Connections
Use 18 AWG or larger wires.
1. Wire according to specifications, following all local ordi-
nances and requirements.
2. Do not bundle the low voltage wires with the ignition
cable, 120 Vac wires, CH Pump or DHW Pump.
3. The low voltage wires for the minimal gas pressure
switch, DHW thermostat, air pressure switch, and gas
valve can be bundled together.
4. Bundle the wires for the fan and join them with the other
24V low-voltage wires.
5. Bundle the wires for the NTC sensors and the PWM
pump control separately.
6. Do not bundle the ionization wire with the high voltage
cables, but it can be joined with the other 24V wires.
High Voltage Cable
1. Always use a grommet when routing the high voltage
cable.
2. Never mix the high voltage cable with other wires.
