COMPUTHERM Q20 Programmable Digital Room Thermostat Instruction Manual
By default setting the thermostat automatically locks the control buttons 30
seconds after the last button has been touched. This setting can be switched
off as described in Chapter 7.
11. BATTERY REPLACEMENT
The average life span of the batteries is 1 year, but frequent use of backlight
can shorten this period considerably. When the
icon indicating low voltage
supply flashes on the display, the batteries should be replaced (see Chapter
5.2.).
The exact time should be set again after the batteries have been replaced,
but the device saves the program that has been loaded as well as the settings
even without batteries therefore there is no need to reprogram or reset them.
Attention! Only high-quality alkaline batteries may be used in the device.
So called durable or long-life zinc-carbon batteries are unsuitable for the
operation of the devices. The
low battery icon appearing on the display
warns the necessity of battery replacement reliably only when high quality
alkaline batteries are being used.
