Programma le Room Thermostat (PRT). When configured for PRT (see page 31) the
Programmable Room Thermostat mainly works by itself and allows the user to have separate
Time and Temperature control of each zone on the wiring centre. Features like Holiday, Party and
Frost mode have to be set on each individual thermostat. The PRT can be configured for global
heat/cool system changeover if your system supports this. This is achieved from a switched input
from the Wiring Centre (see the Wiring Centre Instruction Manual). Communication Connection
(see page 13) is required to use heat/cool changeover function.
Group Control Thermostat. When configured as a Group Control Thermostat (see page 33),
the unit 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
and Frost modes can be selected centrally from the Group Control Thermostat. Holiday mode
will also be applied to a timer if applicable. Communication connections (see page 13) are
required for grouping the Group Thermostats. Thermostats can be also globally changed from
heating to cooling thermostats if your system supports this by using the switched input
connection on the GWC (see the Wiring Centre Instruction Manual) along with the
Communications connections mentioned above.
Group Thermostat. When configured as a Group Thermostat (see page 36), the unit will follow
the time schedule and override modes of the Group Control Thermostat. The Group Thermostat
can have its own programmed temperatures, Manual Override and also be removed from the
group temporarily or permanently. Communication connections are required (see page 13).
Timer. When configured as a Timer (see pages 32 and 34), the unit will operate without
temperature control. In this configuration, the unit can be used as a Hot Water Timer. The Timer
will also follow a Group Control Thermostat when Holiday mode has been activated (requires
communication connections).
