Meitay-tec FMT-24-SUPER-PROG Programmable Thermostat
Installation
The FMT24-SUPER-FP-PROG 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 in such location which represents the room general conditions. Cold or warm air draughts; radiant heat and direct sunlight should be avoided.
General points to follow
- Disconnect power to the main board before installing the unit.
- The unit MUST be fitted into a standard electrical box (Carlon – B114R or similar)
- 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
- Connect the wires as shown in the wiring diagram section of this manual.
- All terminals accept 1×0.5 mm2 /24 AWG.
- Place the thermostat in the electrical box and tighten up the 2 screws.
- Adapt the front frame-panel into its place, by pushing it towards the wall.
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. All wiring to the thermostat is low (safe) voltage and must be separated from power line voltage wiring. 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.
Notes:
- For a non heat pump system with one heat element, leave terminals “W2” free.
- For all system types with one compressor, leave terminal “Y2” free.
- For a heat pump system, “W2” must be connected (Emergency heat).
- RC-RH, – When using one transformer, RC,RH terminals must be shorted.
DIP switch settings
The DIP Dwitch is located on the top of the back side of the thermostat (above the connectors).
