System Overview - Conguration Options
Programmable Room Thermostat (PRT)
When congured for PRT (see page 32) it mainly works by itself and allows the user to have separate Time and Temperature control of each zone on the wiring centre, radiator valve or system receiver. Features like Vacation , Party frost mode have to set on each individual thermostat. All PRTs paired with a wiring centre can also use the global heat/cool changeover function if the your system supports this. This is achieved by using the heat/cool changeover connection on the wiring centre (see note 8 on wiring centre guide).
Group Control Thermostat
When congured for a PRT (see page 32) it can operate as a group control thermostat by assigning a group when pairing with the wiring centre this allows central control of up to 7 group thermostats see below, there can be a maximum of 2 groups per 8 zone wiring centre. Permanent temperature override, Holiday, Party, Frost modes, can be selected centrally from the Group Control Thermostat. Holiday will also be applied to a timer if applicable. The group thermostats can be also globally changed from heating to cooling thermostats if you system supports this by using the switched input connection on the WC (see note 8 on the wiring centre guide).
Group Thermostat
When congured as a digital thermostat and assigning a group when pairing with a WC it can operate as a group thermostat (see page 31), in group mode the group thermostat will follow the time schedule and any override modes of the group control thermostat. At least one group control thermostat is required for grouping see above. The group thermostat can have its own programmed temperatures, manual override and also be removed from the group temporarily or permanently.
Timer
When congured to timer (see page 32) the unit will operate as a timer with no temp control. This can be used for hot water control. The timer will also follow Holiday mode from the group control thermostat if applicable.
