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)

. 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.

SWITCH SELECTED| HEAT ENABLE| UFH PUMP| UFH VALVE| ZONE VALVE ACTUATOR

UFH| On| On| On| On
RAD| Off| Off| Off| On
