meitav-tec FMH-220 Fan-Coil Super 3 User manual

Installation
General points to follow:
- Disconnect power to the main board before installing the unit.
- The unit MUST be fitted into a standard electrical box (Gewiss Box - GW00001481VR)
- The unit should not be installed on an outside wall or where there is an air draft.
- The unit must not be exposed to a direct sunlight.
- The standard height to install this unit is 1.5 meter (5 feet) from the floor.
Installation procedure:
A. Connect the wires as shown in the enclosed wiring diagram. All terminals on accept 1x0.5 mm2 /24 AWG.
B. Place the thermostat in the electrical box and tighten up the 2 screws (Gewiss Box - GW00001481VR).
C. Adapt the front frame-panel into its place, by pushing it towards the wall.
The FMH220 is designed for flush mounting in the room to be
controlled. It should be located where the occupant can easily read
the LCD display and use the controls. If the built in temperature
sensor is being used to measure room temperature, the module
should be placed where the temperature is representative of the
general room conditions. Cold or warm air draughts; radiant heat
and direct sunlight should be avoided.

Wiring
Before connecting or disconnecting any wires, ensure that all power supplies have been switched off and all
wires are potential-free to prevent equipment damage and avoid electrical shock.
Do not run wiring close to transformers or high frequency generating equipment. Complete and verify all
wiring connections before applying power to the controller to which the module is connected.
