Firmware V1.40 - Doku 2.1 06. April 2016
The system centre / store computer does not archive actual temperature values for optional sensors
that are not included in sensor scan.
4.2
Controller function
The sections following describe the various functions of the UA 410 D for control of refrigeration points. Avail
ability of certain controller functions depends on the controller type set on DIP switch S3 (see Section 5.4 Set
ting Controller Type).
The separate controller types are summarized below:
UA 111 X
UA 111 XP
UR 141
Refrigeration Zone 1
Switches with compressor
Majority of supply air sensors
Zone 1
On-off control by room air
sensors Zone 1
Compressor Zone 1 /
Compressor Zone 2
Majority of supply air sensors
Zone 1
Neutral zone pressure switch
(digital inputs)
---
Refrigeration Zone 2
On-off control by supply/return
air sensors Zone 2
On-off control by supply/
return air sensors Zone 2
On-off control by room air
sensors Zone 2
4.2.1
Cooling
Twin control by majority (UA 111 X Zone 1 only)
With the UA 111 X controller, the compressors are controlled as a function of the supply air sensors for the first
temperature zone (see description below, Section 4.2.2.1). The cooling relay energizes as a function of the com
pressors whenever a minimum of one compressor is started.
Majority explained (varying with version):
Version 1.09 and lower
Above Version 1.09
Even number of supply air sensors
1): Half supply air s 1
2): Half supply air sensors
Odd number of supply air sensors
3): Half supply air sensors rounded up
Example:
1):
Total 6 supply air sensors:
4 or more sensors = Majority
2):
Total 6 supply air sensors:
3 or more sensors = Majority
3):
Total 5 supply air sensors:
3 or more sensors = Majority
On-off control by all connected supply air sensors (UA 111 XP Zone 1 only)
Control is made by all supply air sensors of the first zone. The cooling relay de-energizes when temperature
reaches the setpoint (switch-off value) on all connected supply air sensors or the setpoint for antifreeze protec
tion on one supply air sensor. The cooling relay re-energizes when temperature has passed the switching differ
ential on the majority of the connected supply air sensors (e.g. 3 out of 5).
