Introduction
The Uponor Zone Control Module
is a printed circuit control and
diagnostic devicedesigned for use
with Uponor Thermostats, Motorized
Valve Actuators (MVAs), Thermal
Actuators or Zone Valves.
The module provides the following.
•Aconnection 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.

Zone Configurations
The Uponor Zone Control Modules
are available in both three- and four-
zone configurations. Boards can be
ganged together to expand the
number of zones.
Note: The new Zone Control
Modules are note able to be
ganged with older modules.
The new modules have a black
tint base; the old modules
have a green tint base.
Display
Light-emitting diodes (LEDs) indicate
various functions of control. Refer to
Table 3 for LED definitions.
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).

Wiring Instructions
Refer to the following instructions to
properly wire the module.
1. Strip 3⁄8"insulation from the wire.
2. Ensure the wire is fully seated in
the terminal and that it does not
short to adjacent wires.
3. Twist loose stranded wire tightly.
Ensure no loose strands are present.
4. Tighten the terminal nut.
Note: Each terminal is equipped with
ajamb plate for accommodating
stranded wire. When reconnecting
the terminal, it may be
necessary to push the jamb
plate back into place with a
suitable round punch prior to
reinserting the stranded wires.
The maximum number of
connections per terminal is four.
If more than four wires are
required at the terminal, bundle
orwire nut the wires together
and run one wire to the terminal.
Note: Ifusing Uponor 500 Series
controls, use a minimum of
three-wire thermostat wire
for proper functioning of
the thermostat. (Five wire
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
