Viega Multifunctional Thermostat User Guide
UG-HC 566441 1219 Multifunctional Thermostat (EN)
Programmable
Time Periods
Residential
uses 4 time periods:
Wake, Return,
Leave and Sleep.
Commercial
uses 2 or 4 time periods
that appear in the text
field: Occupied and
Unoccupied.
Important:
The low battery indicator is displayed when the AA battery power is low. If the user fails
to replace the battery within 21 days, the screen will only show the low battery indicator
but maintain all functionality. If the user fails to replace the batteries after an additional 21 days
(days 22-42 since first “low battery” display) the set points will change to 55°F (Heating) and 85°F
(Cooling). If the user adjusts these setpoints away from these it will hold for 4 hours then return to
either 55°F or 85°F. After day 42 the batteries must be replaced immediately to avoid freezing or
overheating because the thermostat will shut the unit off until the battery is changed.
