Frequently Asked Questions - FHT-1DA Vemer
How do I install the FHT-1DA thermostat?
First, turn off the power. Connect the wires according to the diagram: L (live), N (neutral), and the load wire. Mount the base on the wall using screws, then snap the front panel into place.
Can I use the FHT-1DA for both heating and cooling?
Yes, the thermostat supports both heating and cooling modes. You can select the mode in the settings menu.
How do I set a weekly schedule?
Press the 'Prog' button to enter programming mode. Use the arrow keys to set the time and temperature for each period (morning, day, evening, night). Repeat for each day of the week.
What does the frost protection function do?
The frost protection function ensures the temperature never drops below a preset minimum (usually 5 °C) to prevent pipes from freezing.
How do I reset the thermostat to factory defaults?
Press and hold the 'Reset' button (located on the side or behind the front panel) for 5 seconds. The display will show 'rES' to confirm.
The display is blank. What could be wrong?
Check if the power is on and the circuit breaker is not tripped. Ensure the thermostat is correctly wired. If the issue persists, the internal fuse may be blown – contact support.
Can I control the thermostat remotely?
No, the FHT-1DA is a standalone thermostat without WiFi connectivity. For remote control, consider Vemer's smart thermostat models.
How do I clean the thermostat?
Use a soft, dry cloth to wipe the surface. Do not use water, solvents, or abrasive cleaners.
What is the maximum load the relay can handle?
The SPDT relay can handle up to 5 A resistive (e.g., 230 V AC, 1150 VA). For inductive loads, the rating is lower.
