LOCATING THERMOSTATS
Place each thermostat in a significant place in the room.
Place at a height of approximately 1.5 m, avoiding direct
sources of heat and undesired draughts. Avoid placing
thermostats close to metal masses and conductor
elements.
BATTERY CHANGE:
When the low battery indicator (3) appears on the thermostat display, you have approximately 2 weeks to
change the batteries.
Remove the front cover of the thermostat by pressing down on the tab at the top using a fine-tipped
tool.
Change the batteries. For a longer working life, use alkaline-type batteries (LR06 AA).

KARESS
Check that:
• No programming / timer is enabled
• The MASTER thermostat is not OFF
• The ECO temperature is not enabled.
• Check the battery level.
Make sure that:
• The operation mode has been changed in the MASTER and in the Air
Handling unit (AHU) thermostat.
• In summer mode, the AHU thermostat must be at a lower temperature
(approx. 2-3ºC) than the MASTER thermostat.
• In winter mode, the AHU thermostat must be at a higher temperature
(approx. 2-3ºC) than the MASTER thermostat.
• There is a close delay (30 s), if this is the last zone to remain open.
• Check the battery level.
