Frequently Asked Questions - GW14705 Gewiss

How to install the GW14705 thermostat?

Installation must be carried out by a qualified electrician. Before any intervention, cut the power supply. Mount the thermostat at a height of 1.50 to 1.70 m from the floor, away from heat sources, drafts and moisture. Connect the wires to the terminals: L (phase), N (neutral), 1 (NO contact), 2 (common), 3 (NC contact).

What is the adjustable temperature range?

The adjustable temperature range is +5 °C to +35 °C. The thermal gradient is ±0.5 °C at 20 °C, ensuring precise regulation.

What does the yellow LED on the thermostat mean?

The yellow LED is a location function. It allows the thermostat to be located in the dark or to check that it is powered.

What does the green LED mean?

The green LED indicates the output status. When it is on, it means that the NO (Normally Open) contact is closed and the load (heating or cooling) is activated.

How to connect the wires to the thermostat?

The connection terminals are: L (phase), N (neutral), 1 (NO contact), 2 (common), 3 (NC contact). The maximum wire cross-section is 2.5 mm². For inductive loads, it is recommended to place an RC filter in parallel.

At what height should the thermostat be installed?

The recommended height is 1.50 to 1.70 m from the floor. Avoid placing it near a heat source, window, door or air intake for accurate room temperature measurement.

Is this thermostat compatible with a boiler?

Yes, the GW14705 can control a wall-mounted boiler, burner, circulation pump or zone valve. Simply connect the output relay (terminals 1, 2, 3) to the device to be controlled.

Can I use this thermostat for cooling (air conditioning)?

Yes, the thermostat has a summer/winter function. In summer mode, it can control an air conditioning system. The connection is similar, but the switching direction can be adapted according to the installation.

How to clean the thermostat?

Use a soft, dry cloth to clean the surface. Never use solvents, alcohol or abrasive products that could damage the device. Disconnect the power before cleaning.

What to do in case of thermostat malfunction?

First check the power supply and wire connections. Make sure the thermostat is correctly positioned. If the problem persists, contact a qualified electrician or Gewiss after-sales service. Do not attempt to repair the device yourself.

Electrical connections

Important: The installation and electrical connecting of the devices and appliances must be undertaken by qualified personnel and in accordance with standards and regulations in force at the time. The manufacture declines to accept any responsibility concerning the use of the products in accordance with particular environmental or installation regulations, as this responsibility rests entirely with the installer.

Warning: Prior to installing the product, ensure the mains electrical supply is disconnected.

With the mains power supply disconnected:

Connect the power supply wires to terminals: n^ L (Line) and n^ N (Neutral).

Connect the wires of the device to be controlled to terminals:

$$ n ^ {\circ} 1 = N A \text {c o n t a c t} $$

$$ n ^ {\circ} 2 = \text {c o m m o n} $$

$$ n ^ {\circ} 3 = N C \text {c o n t a c t} $$

With strong inductive loads (pumps and solenoid valves) it is recommended that an RC filter is connected in parallel to the load.
