INSTRUCTION SHEET

Introduction

The Uponor Zone Control Module
is a printed circuit control and
diagnostic device designed for use
with Uponor Thermostats, Motorized
Valve Actuators (MVAs), Thermal
Actuators or Zone Valves.

The module provides the following.

• A connection to the power supply
transformer

• Interconnections between the
individual thermostats and their
respective MVAs, thermal actuators
or zone valves

• The connection between the end
switches and the pump or boiler relay

The modules are internally fused for
protection from over current or direct
shorts from the power supply
transformer. The end-switch circuit
is also protected from over current
and a 2 amp fuse is factory installed.

Note: Because the E/S terminals are

completely isolated, the modules
no longer require separate
transformers on R and C and
E/S terminals. Pay careful
attention to transformer sizing
if using only one transformer.

Connecting Instructions

Refer to the following instructions
to properly connect the module.

1. Connect modules in series via a
module jumper (provided).

2. Fasten the jumper within the input and
output blocks of the corresponding
modules (see

Figure 1 on page 2).

1. Strip

2. Ensure the wire is fully seated in

he terminal and that it does not

3. Twist loose stranded wire tightly.
Ensure no loose strands are present.

4. Tighten the terminal nut.

Note: Each terminal is equipped with

a jamb plate for accommodating

tranded wire. When reconnecting

s
the terminal, it may be

ecessary to push the jamb

late back into place with a

p
suitable round punch prior to
reinserting the stranded wires.
The maximum number of
connections per terminal is four.
If more than four wires are

equired at the terminal, bundle

is recommended.)

Fuse Replacement

Replace fuses on the board following
the guidelines below.

• 2A fuse for 50VA transformer

• 3A fuse for 75VA transformer

• 4A fuse for 100VA transformer
