APPLICATION
The DT92E wireless digital room thermostat has been designed
to provide automatic temperature control o gas or oil ired boiler
systems, under loor heating, electric heating and zoning systems.
Energy e iciency is addressed by state o the art control
per ormance quali ying it as a Load Compensator.
The DT92E has an ECO button energy saving eature which gives
timed setback or boosts temperatures to reduce energy demand.
This is a TPI (Time Proportional & Integral) control product as
de ined in the Building Regulations, which make boilers operate
more e iciently and provides close, accurate control. This is
continually improved by a sel learning adaptive capability.
The ‘OFF’ setting can be used or rost or hypothermia protection,
assuming the system time control is also switched on.
'Installer Mode' allows control to be matched to the system and
user requirements, adapting minimum on or o times, set point
controls etc.
The volt ree connections are ideal or use with combination
boilers or heating zones.
