- What does it mean if I see a flashing 'Ot' on my Comfort Touch?
This means that OpenTherm® communication between the thermostat and boiler is not responding. Check the thermostat’s connection to the boiler. Please contact your installer if in any doubt.
- What does it mean if I see a flashing 'F' on my Comfort Touch?
This means the boiler has a fault. The ‘F’ symbol may or may not be followed by either a single- or double-digit code. Please consult your boiler’s user manual for an explanation of this fault code. Please contact your installer if this doesn’t resolve your problem.
- What does it mean if I see a flame symbol on my Comfort Touch?
The flame symbol means your boiler is currently heating.
- What should I do if I only see a dot on my Comfort Touch?
It’s up to you whether you want your Comfort Touch to display a fixed room temperature, or not. Adjust this setting on your Comfort Touch’s configuration screen. Press the ‘+’ and ‘–’ symbols simultaneously for two seconds to enter this configuration screen. Using the ‘+’ and ‘–’ symbols, advance to the ‘Stby’ screen. Select either ‘On’ (room temperature displayed by default) or ‘Off’ (room temperature hidden by default).
- What should I do if the screen is blank?
If your Comfort Touch’s screen is blank, then it’s not getting any power. Plug in your boiler and check the cables and connection to the thermostat.
