Selecting the installation site
In order for the thermostat to be operated, the internal temperature sensor
must be protected as far as possible against external influences and
temperature fluctuations. This helps to guarantee reliable measurement of the
room temperature.
The following should therefore be taken into account when considering the
installation site:
- Minimum installation height: 1.5 m above the floor.
- Do not install too close to windows, doors or venti-lation openings.
- Do not install above heaters or other heat sources.
- Do not cover or install behind curtains.
- Avoid direct sunlight and light from lamps.
- Do not install in power strips next to or above components that produce heat, such as dimmers or electronic switches.
Electrical Connections
DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Safe electrical installation must be carried out only by skilled professionals. Skilled professionals must prove profound knowledge in the following areas:
- Connecting to installation networks.
- Connecting several electrical devices.
- Laying electric cables.
- Safety standards, local wiring rules and regulations.
Failure to follow these instructions will result in death or serious injury.
DANGER: RISK OF FATAL INJURY FROM ELECTRIC SHOCK
The output may carry electrical current even when the load is switched off.
- Disconnect the device from the supply by means of the fuse in the incoming circuit before working on the device.
- Make sure the mains input has a 2 A fuse.
Failure to follow these instructions will result in death or serious injury.
Wiring options
- a. Volt-free wiring. Normally open
- b. Switch live wiring with L-COM jumper wire. Normally open
- c. Volt-free wiring. Normally closed
- d. Switch live wiring with L-COM jumper wire. Normally closed
- A Output: max. 2 A resistive load
- B Input: setback / presence detection C Heating / Cooling input
Mounting
Presets: A preset must be selected after the first power up or reset.
- Preset: Configuration
