directly to the timer then a link needs to be fitted between IN and OUT.
Optional Hot Water Motorised Valve: Used if timed hot water is required.
Optional Overheat Thermostat: Used for connecting a pipe thermostat to
prevent over temperature water damaging sensitive floors. Remove the link
and connect the pipe thermostat so it is Normally Closed. The pipe stat will
open if overheating occurs and
the UFH pump will stop running.

Thermostat Grouping
The thermostats can work as individual units or in groups. There can be up to 2 groups of

Actuator Connections
Actuator connections corresponding to the thermostat
connections. Up to 2 cables can be used in each
connection (4 Actuators per Zone) If more, that number
needs to be connected, then an external junction box
will be needed. A maximum of xxx actuators can be
connected to a zone in this manner.

This must be carefully removed or

Dip Switch Set Up
In order for the wiring centre to be able to control UFH
and Radiators, there is a need to turn off the UFH pump for
a zone when that zone is to be used for radiators.
Eg. When fitting a zone for radiators or towel rail then the
Dip Switch for that zone should be switched to OFF.
The Dip Switches for this are located under the front lid.
When the zone switch is in the ON position the UFH pump
will run when that zone is calling for heat along with the
boiler. When it is in the OFF position then the UFH pump will
not run but the boiler will fire.
There are three other function switches as well.
Pump & Boiler delay: This gives a three minute delay to
allow actuators to open before the boiler fires.
Pump Only Delay: Delays only the UFH pump from firing
for three minutes.
Actuator NC or NO: This refers to Normally Open or
Normally Closed. This should be set to NC for JG products.
