Frequently Asked Questions - CalorMATIC B VAILLANT

How do I set the time on my CalorMATIC B thermostat?

Press the Menu button, navigate to Clock using the arrow keys, then set hours and minutes with the + and - buttons. Confirm with OK.

What does the 'CH 1' value in the chart mean?

CH 1 refers to Channel 1 (heating circuit 1). The value (e.g., 100) indicates the temperature setting or a percentage related to the desired comfort level.

How do I program the weekly schedule?

Enter Program mode via the menu. Select a day or group of days. For each time period (e.g., Morning, Day, Evening, Night), set the start time and target temperature.

Why is the display showing 'b 20'?

The 'b' likely stands for battery and 20 is the battery voltage indicator (e.g., 2.0V). A low value (below 10) means batteries need replacement.

How do I replace the batteries?

Remove the thermostat from its wall plate. Open the battery compartment on the back. Insert two AA alkaline batteries (1.5V) observing polarity. Reattach the thermostat.

Can I use this thermostat with any Vaillant boiler?

The CalorMATIC B is compatible with most Vaillant boilers using a wired connection (usually 2-wire). Check your boiler manual for compatibility.

What does the 'Prog.' value mean?

'Prog.' refers to the program number or program setting currently active. Values like 50 indicate a specific pre-programmed temperature profile.

How to reset the thermostat to factory settings?

Press and hold the Menu and OK buttons simultaneously for 5 seconds until the display resets. All settings will be lost.

What does the symbol '1...7' mean on the chart?

It likely denotes the day of the week (1=Monday ... 7=Sunday). The value (10) may represent a temperature or program number for that day.

Is the thermostat backlit?

Yes, the CalorMATIC B has an LCD display with backlight that activates briefly when a button is pressed for better readability in low light.
