Climate Control Zoning System II installation and operation manual | Chapter 3 – Installing the base unit l 11
Connecting actuators to the base unit
Each thermostat can control one or more channels.
To simplify installation and maintenance, Uponor
recommends that actuators controlled by the same
thermostat wired in sequence to the channels.
Connect the actuators to the base unit as follows.
1. Lead the cables from the actuators through cable entries
in the bottom of the base unit frame (see Figure 3-12).

2. Press, without turning, with a thin screwdriver,
on the white button of the quick connector.
3. Insert a wire in the quick connector.

Important! Identify the room supplied by each loop
on the manifold and determine which channel it must
be connected to.

1. Study the wiring diagram in the end of the manual or inside
the cover of the base unit, to locate the connector positions.
2. Ensure power is disconnected from both the base unit and
the circulation pump.
3. Remove the screw and open the cover for the optional
connections compartment.
4. Route the wires to/from the pump relay via a cable entry.
5. Connect the wires to/from the pump relay as shown and
connect to the terminals labeled PUMP.
Important! There is no power in the controller to
supply the pump. The pump connector in the base unit
provides only a dry contact to switch off and on the
power connection to the pump.
6. Secure the wires properly inside the enclosure.
7. Close and secure the lid to the optional
connections compartment.
A circulation pump is now connected to a relay module
and activated.
