Introduction
The Mixing Expansion Module 441 is designed to operate any of the tekmar 3-way and 4-way brass mixing valves from
type 710 through type 724. The 441 provides 6 N•m (53 in•lbs) of torque over a 90° rotation. The 441 is controlled through
digital communication on tekmarNet®4 systems. The 441 requires the use of a tN4 System Control that includes a mix
temperature bus.

Sequence of Operation
ON

Automatic Operation
Automatic operation of the mixing valve
requires the red dial on the front of the 441
to be set to the “AUTO” position.
The tN4 System Control determines the target
mix supply water temperature based on its
settings and the requirements of the tN4
thermostats and tN4 setpoint devices on the
mix tN4 bus. The 441 uses the Mix Supply
sensor to measure the water temperature and
then operates the mixing valve to maintain the target water
temperature. The 441 powers the system pump output with
24 V (ac) whenever a tN4 thermostat or tN4 setpoint control
calls for heat on the tN4 mix bus and that tN4 device’s Heat
1 Pump (or Heat 2 Pump) setting is set to On.
The position of the mixing valve is indicated by the red
stripe on the hand wheel.
Manual Operation
Manual operation of the mixing valve requires
the red dial on the front of the 441 to be set
to the “MAN” position.
To change the mixing position, rotate the hand
wheel of the 441.
The position of the mixing valve is indicated
by the red stripe on the hand wheel.
DIP Switch Setting
The 441 has a DIP switch located inside the wiring
enclosure.
Step 1: Remove the hand wheel.
Step 2: Remove the two screws.
Step 3: Remove the front cover.
The DIP switch selects the direction of rotation to open
the mixing valve.
In the OFF position, the actuator moves in the clockwise
direction to open the valve.
In the ON position, the actuator moves in the counterclockwise
direction to open the valve.
