Sensor C (moisture) is connected to 12 and 13.

A possible remote control unit is connected to 9 and 14.

Sensor

If the thermostat is going to be used as a oor heating thermostat, connect the room sensor as A, and the oor sensor as B. If you are installing a oor that requires over heating protection, connect the room sensor as A and the over heating protection as B.

Install the oor sensor in a spiral tube recessed in the oor. The end of the tube must be sealed to facilitate possible replacement of the sensor.

Place the room sensor so that it is not exposed to direct sunlight or draught. If the room sensor is installed in an appliance box, it must be sealed to prevent the air temperature being aected by draught.

For other types of operation and control, the temperature sensor can be installed as either A, B or A+B. For operation type max/min, the moisture sensor can also be installed as sensor C. You give the location of the sensor in the START MENU. The high temperature sensor is recommended for temperatures above +75 °C. Only one high temperature sensor can be connected. It must always be connected as B, terminal block 7 and 8.

INTRODUCTION

Introduction

The manual, like the thermostat, is divided into four operation modes so that you only need to read about the functions you will use. The thermostat operation mode can only be installed in the start menu, which is shown the rst time the thermostat is started (read more about the start menu on page 8) or after it has been reset.

Four operation modes

HEATING

Operation mode storerooms and such like. With this operation mode, you can regulate the heating within a temperature range of +5 °C to +45 °C. The thermostat can be used as a oor thermostat, room thermostat or room thermostat with over heating protection for wood oors. The energy saving program is primarily adapted for home and oce environments, but can also be used for regulating heating levels in, for example, storerooms.

COOLING

Operation mode storerooms and such like. In this operation mode, the thermostat works as a room thermostat for regulating air conditioning or other cooling within a temperature range of +5 °C to +45 °C. Energy saving programs are primarily adapted for home and oce environments but can also be used for cooling, for example, storerooms.

INDUSTRY

Operation mode temperature of industrial processes, high temperatures or for the frost protection of sensitive installations. Temperatures within the ranges -15 °C to +75 °C and 0 °C to +170 °C can be regulated in this mode or the range can be limited to between -10 °C and +15 °C for frost protection purposes. It is also possible to adjust temperature hysteresis and set upper and lower temperature alarms.

HEATING is used in homes, oces,

COOLING is used in homes, oces,

INDUSTRY is used to regulate the

MAX/MIN

The Max/Min operating position is mainly used to keep roof and ground surfaces free of snow and ice. The temperature range is adjustable between -20 °C and +10 °C. For the best results and the best energy saving, combined temperature and humidity control should be used in the Max-/Min position, with associated Roof Sensor or Ground Sensor.

Operation mode Heating

Heating mode is used in homes, oces, storerooms and such like. With this operation mode, you can regulate the heating within a temperature range of +5 °C to +45 °C. The thermostat can be used as a oor thermostat, room thermostat or room thermostat with over heating protection for wood oors. The energy saving program is primarily adapted for home and oce environments, but can also be used for regulating heating levels in, for example, storerooms.

Set point TEMP

The set point setting is under TEMP in the temperature menu. Set the required temperature by pressing

or and conrm by pressing . The set point can be set to an accuracy of 0.5 degrees within the range +5 °C to +45 °C; it is preset to+22 °C.

Over heating protection OH PROTECTION

Over heating protection works as a oor temperature limiter; if you have a wood or laminate oor, you must always use a room sensor with over heating protection to ensure that the oor material is safeguarded against over heating and damage.

Over heating protection is under

OH PROTECTION under TEMP. The limitation can be

set between +5 °C and +45 °C. The factory setting is +35 °C, which gives a surface temperature of about +27 °C.

Page 12

The surface temperature is an average value and varies somewhat depending on the material and the thickness. Denser (harder) wood insulates less than softer wood, which increases the surface temperature. Also, the thinner the oor, thehigher the surface temperature.

Two sensors are required for over heating protection: a room sensor (sensor A) and an over heating protection sensor (sensor B).

Program menu PROGRAM

A smart way of saving energy is to adapt the heating to suit the needs throughout the day and, for example, lower the temperature when there is nobody home. There are four dierent ways of lowering the temperature: two preset programs for home or oce environments, one program for personal settings and a frost protection program. There is no need to consider the heating time when programming since the thermostat has an adaptive function that applies this automatically.

The programs are in the using

Program for hotel environments HOTEL

This program allows you to control the heating via external card readers with a delay time, since the thermostat has an integrated time relay function. The temperature settings change automatically when the hotel guest comes into or leaves the room and the delay time is fully adjustable, making it easy to decide how long the heating is to keep running after the guest has left the room.

The Hotel program can be found under

HIGH TEMP

The temperature can be set to between +5 °C and +45 °C. The thermostat reacts based on the temperature that is set in the manual program, where the factory setting is +25 °C. If the temperature is changed in the manual program, or the set point is changed in the

TEMP menu, the thermostat will react based on the

new temperature.

REMOTE CONTROL

The Hotel program is controlled by a remote control device, such as a card reader, connected to the designated terminal blocks. The thermostat switches from low to high temperature when the device’s input circuit closes. When the input circuit opens, the thermostat returns to the “low” set point after the set time.

Program menu PROGRAM

A smart way of saving energy is to adapt the air conditioning to the needs throughout the day and, for example, lower the temperature when there is nobody there. There are four dierent ways of raising the temperature: two preset programs for home or oce environments, one program for personal settings and a holiday program.

There is no need to consider the cooling time when programming since the thermo stat has an adaptive function that applies this automatically.

Temperature hysteresis TEMP HYS

The thermostat can be prevented from switching on and o the eect too often by increasing the temperature hysteresis.

The hysteresis is the range the current value is permitted to deviate from the set point without the thermostat switching on or o the eect. A set hysteresis value of 0.3 °C and a set point of +40.0 °C means that the temperature (current value) can vary between +39.7 °C and +40.3 °C.

The hysteresis can be increased if the system does not operate smoothly, i.e. the thermostat continually switches on and o the eect. Excessive switching increases wear on the relay and reduces the service life of the thermostat considerably.
