Wiring Centre Terminals

Power Supply

• L 230Vac Live
• E Earth
• N Neutral

Programmer

• L 230Vac to the programmer.
• E Earth to the programmer.
• N Neutral to the programmer.
• 1 Zone 1 output from programmer to the wiring centre. 2 Zone 2 output from programmer to the wiring centre. 3 Zone 3 output from programmer to the wiring centre. 4
• Zone 4 output from programmer to the wiring centre.

Thermostats (Zone 1 to Zone 8)

• L Live supply to the thermostat.
• 1 Timed switch live to room stat from programmer zone 1. 2 Timed switch live to room stat from programmer zone 2. E Earth.
• N Neutral supply to the thermostat.
• S/L Switch live from the thermostat to the wiring centre.
• Note: With thermostats 1 to 8, you have an option of; one of two time inputs.

Thermostats (Zone 9 and Zone 10)

• L Live supply to the thermostat.
• 1 Timed switch live to room stat from programmer zone 1 2 Timed switch live to room stat from programmer zone 2 3 Timed switch live to room stat from programmer
• zone 3 4 Timed switch live to room stat from programmer zone 4 E Earth.
• N Neutral supply to the thermostat.
• S/L Switch live from the thermostat to the wiring centre.

Note: With thermostats 9 & 10, you have an option of; one of four time inputs.

Heat Enable (Boiler / Heat Pump On)

• LS Live supply
• E Earth
• LR Live return

This is a volt free relay which is switched on when there is a call for heat If 230V is applied to terminal LS and there is a call for heat, 230V will come back on terminal LR.

UFH Pump (Underfloor Heating Pump)

• L 230Vac Live
• E Earth
• N Neutral

When an underfloor heating zone calls for heat, 230V is sent to the underfloor heating manifold pump. Best practice is to wire the underfloor heating manifold pump through a high limit thermostat which is mounted on the manifold.

UFH Valve (Underfloor Heating Valve)

• GR Grey Switch Live
• OR Orange Permanent Live
• L Live
• E Earth
• N Neutral

When an underfloor heating zone calls for heat, 230V is sent to the Underfloor heating valve. The valves auxiliary contacts are wired to the GR and OR terminals.
Note: Please refer to factory default settings on page 1.

Actuators (Zone 1 to Zone 8)

• L 230V Live supply to the actuator.
• N Neutral supply to the actuator.

There are two terminals marked L & N for each zone.

Actuators (Zone 9 and Zone 10)

• L Live supply to the actuator.
• N Neutral supply to the actuator.

There are two terminals marked L and two terminals marked N for each zone. Both zones 9 and 10 have a switch associated with each zone. This allows the installer to use these zones as underfloor heating zones or radiator / hot water zones.

Operation of Zone 9 & 10 UFH – RAD / HW switches

If set to UFH – When the thermostat calls for heat, the actuator, boiler and pump / valve outputs are enabled. If set to RAD / HW – When the thermostat calls for heat, the actuator is enabled. To enable the boiler output, the actuator auxiliary contacts (Grey and Orange wires) must be connected to the LS & LR terminals of the Heat Enable.
