Electrical Application 441 E1 Description: The Mixing Expansion Module 441 connects to a Zone Manager 335, 336 or 337 which in turn is connected to a tN4 system control. The 441 controls the supply water temperature of the tN4 bus that it is connected to.
PAGE 5
Electrical Application 441 E2 Description: The Mixing Expansion Module 441 connects to a tN4 device such as a thermostat which in turn is connected to a tN4 system control. An external transformer provides 24 V (ac) power, and a Relay 003 is used to switch the system pump.

Wiring the Control • 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.
