Programming aid for F17-C controller

(The F17-C is supplied as standard with Warm Tiles kit WT28)

Note. This sheet has been produced to assist in the programming of the F17-C controller. It breaks down the basic features of the thermostat and is designed to be easy to follow. This document will help you to:
Set time and day.
Set setback programmes and temperatures.
Note. This document should only be used in conjunction with the user manual supplied.

To set time and day

  • Turn power to the thermostat on- display flashes 00.00
  • Press and hold button until display reads SET (approx. 5 seconds).
  • Turn button clockwise until display reads 2 on the bottom left hand side. Press button once.
  • The preset time is now flashing, adjust to the correct time by turning the button clockwise. When displayed time is correct, press button to set.
  • Now adjust the number on the bottom of the display by turning the button clockwise (1=Monday, 2 =Tuesday etc). Press button once.
  • Turn button clockwise until display reads END. Press button once.

To set-up setback programmes

These programmes allow you to setup times when you want the under floor heating system to maintain a lower or higher temperature. The most common use for this is through the night where by setting a very low setback temperature you can effectively turn the heater off. The F17-C controller allows you to setup up to 8 setback programmes for any day. The following example shows the programming of 1 setback programme to come on at 10.00pm in the evening, and turn off at 7.00am in the morning seven days a week. (If you require more complex setback programmes please refer to user manual supplied)

  • Press and hold button until display reads SET. Press button once.
  • Turn button clockwise until display reads P1 (this is program 1 of 8). Press button once.
  • Turn the button clockwise until display reads 1234567 along the bottom. This indicates that this setup programme will run every day of the week. Press button once
  • With the moon displayed, turn the button clockwise until display reads 10.00pm. Press button once when correct.
  • With the sun displayed, turn the button clockwise until display reads 07.00am. Press button once when correct.
    Note. P1 is now setup for every day.
  • If required there are 8 setback programmes. For more complex setback programming please refer to user manual.
  • Turn the button clockwise until the display reads END. Press the button once.

To Set The Setback Temperature

This is the temperature that the thermostat will maintain during setback operation. To change this press and hold the button until SET appears. Turn the button clockwise until 3 appears at the bottom of the display. Press the button. A temperature flashes, adjust this by turning the button clockwise. Press to accept. Turn the button clockwise until END is displayed, press once. Note. The temperature set here is the same for all setback programmes.

To Set Comfort Temperature

This is the temperature that the thermostat will maintain when not in a setback programme. The thermostat has a preset comfort temperature of 21.5C, to change this:
From the automatic operation (clock display) screen, rotate the button clockwise, the screen changes and a thermostat appears at the top of the display. Adjust the temperature by turning the button clockwise and press once to set. Note. As a guide to setting the comfort temperature, the 'European norm' is 24C

To Switch The Thermostat Off

From the automatic operation (clock display) screen, press the button twice and the display changes to OFF. Now the heater will remain inactive, and any setback programmes setup will not operate. To turn the thermostat back on, simply press the button once.
Note. Once the thermostat is switched back on, the setback programmes will reactivate.
