ST621TX INSTRUCTION MANUAL
PROGRAMMING THE ST621TX
The ST621TX offers great versatility with its
programming options, allowing the user
to programme the ST621TX to operate
on an individual, 5/2 or 7 day control
cycle. The programmable thermostat has
a default set of Programmes that have
been designed to meet the needs of most
users. If these default programmes are
not suitable for your particular situation,
reprogramming the ST621TX with your
own settings is a very straightforward
operation.
To start programming the ST621TX, press
the OK key when in NORMAL mode. This
will by default select the PROGRAM menu
- press the OK key once more to start the
programming process.
Initially, the Weekdays will be selected
and flashing – you can scroll through all
the various options for day selection (Weekdays, Weekend, 7 days, or individual days) by using the
Touch Ring. As usual, pressing the OK key will select the desired option.
