mode
Current set point value
Comfort
Basic set point value + set point value offset + dead zone
Standby
Basic set point value + set point value offset + dead zone + increase in standby
mode
Night
Basic set point value + set point value offset + dead zone + increase in night
mode
Frost/heat
protection
Programmed set point value for heat protection mode
Example:
Cooling in comfort mode.
The room temperature is too high and Cheops control has switched to cooling operation
Calculation:
Current set point value = basic set point value + set point value offset + dead zone
= 21°C -1K +2K
= 22°C
Changing to standby mode causes a further increase in the set point value (energy saving) and
gives rise to the following set point value.
Set point value = basic set point value + set point value offset + dead zone + increase in
standby mode
= 21°C - 1K + 2K + 2K
= 24°C
5.2 Set point value offset
The current set point value on Cheops control can be adapted in 3 ways:
• step by step by the red (+) and the blue (-) key
• in increments via Object 5 " adjustment of set point temperature "
• directly via Object 1 " Manual shift of set point value "
The differential between the set point value offset and the Basic set point value is sent by
Object 1 at each change (e.g. -1.00).
The offset limits are specified on the "Operation" parameter page by the "Maximum set point
value offset" parameter and apply for all 3 types of set point value offset.
