DEVI 532 Electronic Thermostat Installation Guide

DEVI 532 Electronic Thermostat Installation Guide

Introduction

DEVIreg™ 532 is an electronic thermostat provided with a 2-pole switch, a room sensor to control the room temperature, and an additional fioor sensor to limit the maximum fioor temperature. It can be either fiush-mounted or surface mounted.

The thermostat has a button for adjusting the temperature setting with a scale from (  ) 5-35°C. Furthermore, it has a LED indicator showing standby periods (green light) and heating periods (red light).

Safety Instructions

Make sure the mains supply to the thermostat is turned off before installation.

IMPORTANT: When the thermostat is used to control a fioor heating element in connection with a wooden fioor or similar material, always use a fioor sensor and never set the maximum fioor temperature to more than 35°C.

Please also note the following:

• The installation of the thermostat must be done by an authorized and qualified installer according to local regulations.
• The thermostat must be connected to a power supply via an all-pole disconnection switch.
• The sensor is to be considered as live voltage. Have this in mind if the sensor must be extended.
• Always connect the thermostat to continuous power supply.
• Do not expose the thermostat to moisture, water, dust, and excessive heat.

Mounting Instructions

Please observe the following placement guidelines:

Place the thermostat at a suitable height on the wall (typically 80-170cm.).

In wet rooms, always place the thermostat according to local regulation on IP classes.

Do not place the thermostat on the inner side of an exterior wall.

Always install the thermostat at least 50 cm. from windows and doors.

Do not place the thermostat in a way that it will be exposed to direct sunlight.

Note: A fioor sensor enables a more accurate temperature control and is recommended in all fioor heating applications and mandatory under wooden fioors to reduce the risk of over-heating the fioor.

• Place the fioor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings.
• Equally distant and >2cm from two heating cables.
• The conduit should be fiush with the fioor surface – countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm

Follow the steps below to mount the thermostat:

1. Open the thermostat:
   
   

   • Press the release tab in the bottom of the thermostat using a fiat object.
   • Carefully detach the front cover.
   • Carefully detach the frame.

2. Connect the thermostat according to the connection diagram.

The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.
Note: Always install the fioor sensor in a conduit in the fioor.

3. Set the maximum fioor temperature between 20 °C and 50 °C by turning the screw with temperature indications in the upper left corner.
4. Mount and reassemble the thermostat:
   • Fasten the thermostat to a fiush-mounting box or a surface-mounting box by driving the screws through the holes in each side of the thermostat.
   • Install the frame and front cover in the reverse order of disassembly.
5. Turn on the power supply.

Settings

How to change the minimum and maximum fioor temperatures.

1. Remove the adjustment button.
2. Move the pins to the desired positions.
3. Put the adjustment button back in place.

Note: Please be aware of the following:

• The fioor temperature is measured where the fioor sensor is placed.
• The temperature of the bottom of a wooden fioor can be up to 10 degrees higher than the top.
• Floor manufactures often specify the max temperature on the top surface of the fioor (usually 27-28 ˚C).
• By default, the maximum fioor temperature is set to 35 °C.
• Always use a fioor sensor or a room + fioor sensor combination to control fioor heating. Without a fioor sensor, the temperature control may be less accurate and you risk overheating the fioor.
