This parameter indicates the maximum permitted offset and the increment per keystroke (or
per activation of Object 6).
5.2.1 Incremental set point temperature adjustment via keys
Each time the blue key is pressed, the set point value is decreased by one increment.
Each time the red key is pressed, the set point value is decreased by one increment.
When the max. permitted offset is reached, further keystrokes have no effect.
5.2.2 Incremental set point temperature adjustment via Object 6
Each time a 1 is sent to Object 6, the set point value is decreased by one increment.
Each time a 0 is sent to Object 6, the set point value is increased by one increment.
When the max. permitted offset is reached, further send actions have no effect.
5.2.3 Direct set point temperature adjustment via Object 1
In this case, the set point value is changed by sending the desired offset to Object 1.
This involves the differential (may be preceded by a minus sign) being sent in EIS5 format.
The offset always relates to the programmed and not to the current set point value.
Example – Basic set point value 21°C:
If a value of 2.00 is sent to Object 1, the new set point value is calculated as follows:
21°C + 2,00K = 23.00°C.
To then bring the set point value to 22°C, the differential is resent to the programmed basic
set point value (here 21°C), in this case 1.00K (21°C+1.00K=22°C)
5.3 External interface
The external interface consists of inputs E1 and E2.
Both inputs are routed through the Cheops connection line.
The use of these inputs (presence sensor or actual value) is specified on the "Settings"
parameter page.
The inputs themselves are configured on the "External interface" parameter page.
