1. Introduction
The Vysa-Therm™ 3000 is the most advanced thermostat available in the market today. Vysa-Therm™
3000 has the largest microprocessor available and is packed full of features to make life simple for the
installer and user alike.
The Vysa-Therm™ 3000 is the simplest thermostat to install and
never programme
. The default
programme has been optimised for economy and comfort suitable for typical lifestyles. The Vysa-
Therm™ 3000 has a high capacity 3V Lithium coin battery to protect the factory pre-set time and date so
that the installer / user need not enter them during installation.
There are two modes of operation; timed or un-timed.
The operation mode is initially selected by the DIL switches during installation but can be changed later
under the engineer menu without having to open the control.
When
timed operation
is chosen the control uses a real time clock and timer periods to change the
temperature between the comfort temperature and the savings temperature.
When
un-timed operation
is chosen the control is set to the required temperature using
S
and
T
and
controls to this temperature until it is manually adjusted.
