Application & Features
Typical System
Connections
The TP75 is a true seven-day programmable
thermostat incorporating many useful features.
An optional Optimum Start function will enable a
required comfort temperature to be achieved by
a programmed time, without wasting fuel
because the heating plant started earlier than
necessary. The chrono-proportional control logic
ensures optimum comfort with minimal fuel
consumption.
The basic model incorporates a temperature
sensor within the casing, but a remote sensor
version is also available. Both can be converted
to operate as an electronic thermostat, controlling
at a constant, user selected, temperature. The
Holiday Mode uses this temperature for a
selected number of days, before automatically
returning to programmable thermostat mode.
Versions are available for use with a third- party
telephone line switching device so that frost
mode or holiday mode can be cancelled whilst
away from home.
