Introduction 1.1
Congratulations! You have chosen a Sauter heating controller. The equitherm
®
EQJW245 is a quality product from one of the leading manufacturers of control
technology products for the heating, ventilation and air conditioning industry.
The EQJW245 is a compact, weather-compensated heating controller used to
regulate fl ow temperatures and domestic water preparation. In automatic mode,
the EQJW245 reduces the room temperature during the night (Reduced mode)
by means of switching commands from the weekly time switch (weekly switching
programme), and during the day it switches to the normal temperature. Domestic
water preparation is switched on or off via another switching programme. There
is a choice of two adjustable temperatures for domestic water. The EQJW245
is suitable for buildings of all types. A fi xed basic programme (factory setting)
ensures that commissioning is simple. Any adaptations to the heating system
which might be needed are implemented using SERVice parameters. Automatic
summertime/wintertime change-over eliminates the need for residents to adjust
the time twice a year. The equitherm
®
EQJW245 incorporates a variety of
protective functions such as the anti-frost function and the pump anti-Yesmming
facility. Additional functions such as automatic switch-off are also implemented.
For every installation, these features ensure optimal comfort with the minimum
use of energy.
Analogue or digital room operating units can be connected to the EQJW245,
enabling convenient remote control of the controller from the living room.
A programmable output is available for additional tasks. For example, it may be
used as a pilot timer output, a signal for a collective fault alarm or for activating
a central heating pump or domestic water circulation pump. The communication
interface makes it possible to network several controllers, connect to a control
station and/or send alarms to a mobile telephone via SMS.
