7 Set Back Function
During a programmed switch OFF period it is possible to have the unit automatically heat (if electric heating is fitted or it is a heat pump unit) if the
temperature falls below a preset LOW limit, or cool if it rises above a preset HIGH limit.
NOTES:
z If either set back temperature is set to anything other than --EC, the indoor unit's fan will run at low speed during the switched OFF period in order
to circulate air over the sensor.
z The set back function will apply to all 7 days of the week, even if the unit does not normally run, say at weekends.
z Active set back is indicated by a double flash of the red LED on the unit, repeated at 15 second intervals.

c. If no temperature has been set, press the + (•) button first, then the + or - (• or – ) buttons to select the minimum
temperature to which the room should fall before the unit switches on in heating mode.
