1 General information

1.1 Introduction

Congratulations! You have chosen a Sauter heating controller. The

equitherm



EQJW 145 is a quality product from one of the leading

manufacturers of control technology products for the heating, ventilation and

air conditioning industry.

The EQJW 145 is a compact, weather-compensated heating controller used

to regulate flow temperatures and domestic hot water preparation. In

automatic mode, the EQJW 145 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 hot water preparation is switched on or off via

another switching programme. There is a choice of two adjustable

temperatures for domestic hot water. The EQJW 145 is suitable for buildings

of all types. A fixed 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



EQJW 145 incorporates a

variety of protective functions such as the anti-frost function and the pump

anti-jamming 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 EQJW 145,

enabling convenient remote control of the controller from the living room.

A programmable output is provided for additional tasks. For example, it may

be used as a pilot timer output, as a signal for a collective fault alarm, and to

activate a circulating pump for domestic hot water. The communication

interface makes it possible to network several controllers, to connect to a

control station and to send alarms to a mobile telephone via SMS.

1.2 Safety information

Special care is required in order to prevent injuries, damage by fire or

damage to equipment. After the device has been installed by a specialist in

accordance with the Installation Instructions enclosed with it (MV506103),

please read these instructions on operating it. Local regulations must be

followed during installation. The controller is not a safety-relevant component.

The anti-frost, overheating protection and flow temperature limitation

functions do not replace the relevant safety equipment.

2.4 Input knob

You can use the input knob to scroll through menus, and

to select or change values. Unless explicitly described

otherwise, you can scroll through or change

menus/values in a ring structure. There is no 'limit stop'

for adjusting values or scrolling.

The input knob has a key function, i.e. you can press it.

This is used to select the parameter just shown for

changing, or to confirm a flashing value, or to access a

lower menu level.

2.5 ESC key

Press the ESC key to cancel operations, or to return from

a lower menu item to the next level up.

2.6 Display

The device has an LC display (see 2.1), which can show various items of

information at the same time. The next illustration shows what the symbols

mean:
