•
• Use a Phillips screwdriver to remove the two screws on the top of the actuating motor to remove the wiring cover.
•
• All electrical wiring enters the actuating motor through the 1/2” (13 mm) conduit hole on the bottom. Standard 18 AWG
solid wire is recommended for all connections to the motor terminals.
•
• When using conduit, a conduit wye is required to allow the separation of the sensor wires from the R, C, tN4 and Pump
wires.
•
• Strip all wiring to a length of 3/8 in. or 10 mm for all terminals.
•
• Refer to the current and voltage ratings at the back of this brochure before connecting devices to this control.
Caution: The mixing expansion module 441 is not suitable for use with rigid conduit.
24 V (ac) Power
Wire 24 V (ac) to terminals C and R.
If a Zone Manager is used:
•
• Connect C on the 441 to C on the Zone Manager.
•
• Connect R on the 441 to R on the Zone Manager.
If a 24 V (ac) transformer is used:
•
• Connect C on the 441 to C on the transformer.
•
• Connect R on the 441 to R on the transformer.
tN4 Communication
Wire the tN4 communication to terminals tN4 and C on the
desired tN4 mix temperature bus.
If a Zone Manager is used:
•
• Connect tN4 on the 441 to Zone Group A or B tN4 on the
Zone Manager. The C terminal is already connected.
If a Zone Manager is not used:
•
• Connect tN4 on the 441 to tN4 on another tN4 device
on the same mix tN4 bus.
•
• Connect C on the 441 to C on another tN4 device on
the same mix tN4 bus.

The 441 provides a 24 V (ac) powered signal to activate
a system pump. The system pump is powered off either a
Zone Manager Zone Group Pump or off a 24 V (ac) coil
Relay 003.
When connecting to a Zone Manager 335:
•
• Connect the Pump terminal on the 441 to terminal 3
labeled Pmp A on the 335. This activates Zone Group
Pump A.
When connecting to a Zone Manager 336:
•
• Connect the Pump terminal on the 441 to terminal 3 labeled Pmp A on the 336. This activates Zone Group Pump A.
When connecting to a Zone Manager 337:
•
• Connect the Pump terminal on the 441 to terminal 3 labeled Pmp B on the 337. This activates Zone Group Pump B.
When using a Relay 003:
•
• Connect the Pump terminal on the 441 to terminal 2 on the Relay 003.
•
• Connect C on the 441 to terminal 7 on the Relay 003.
•
• Line voltage is connected to terminal 8 on the Relay 003.
•
• Switched line voltage for the pump is available on terminal 6 on the Relay 003.
