Installation and user guide
The HeatMax™ UFH wiring centre is a 4-zone wiring module that has all of the electrical
connections for warm water underoor heating systems.
Key features:
- It connects HeatMax™ room thermostats to the corresponding HeatMax™ zone
actuators
- The zone actuator state (open / closed) is indicated by green LEDs
- The boiler and pump state (on / off) is indicated by red LEDs
- It includes a volt-free contact to operate external items such as combination boilers
- Additional zones can be added by plugging in HeatMax™ UFH wiring centre
extensions
- DIN rail or wall mountable

How it works
The HeatMax™ UFH wiring centre works in the following ways:
Main function
When there is heating demand from at least one thermostat, a relay is energised,
opening the 2-port zone valve. This then energises further relays, turning on the pump
and boiler control signals.
Alternatively
If there is no 2-port zone valve used, the link wire S1-S2 should remain connected; and
in this case all devices (pump, boiler and zone valves) will work simultaneously.
External clock option
External time clock or programmers are connected to the mains supply terminals. The
entire UFH system will switch on and off following the programme from this clock.
Installation
NOTE: Do not make any electrical connections until you are certain that the power is
switched off.
Tools required
• Phillips screwdriver (for cover removal or replacement)
• Slotted screwdriver with a 2.5mm or 3mm blade (for making terminal connections)
• Screwdriver to suit mounting screws (not supplied)
Step by step guide
1. Using the Phillips screwdriver, undo all of the cover screws on the HeatMax™ UFH

4. Using a screwdriver with a 2.5mm or 3mm blade, make all power, pump, 2-port zone
valve, boiler, programmer, thermostat and zone actuator terminal connections,
depending on the heating conguration, boiler type and control (see the following
wiring diagrams)
5. Replace the HeatMax™ UFH wiring centre cover and replace all of the cover screws
