Alarm thermostat

AKC 114G
The function is used for sounding the alarm before the product temperature at the refrigeration
site becomes critical.
You can set alarm limits and time delays for high and low temperatures. Alarm will be given if
the set limit is exceeded, but not until the time delay has expired.
The alarm sensor may be chosen independently of the sensor used for the thermostat
function.

Alarm sensor

The alarm sensor can be selected for S3, S4, or a weighted value of both of them.
The alarm thermostat is defined by keying a figure between 0 and 3:
0: Alarm thermostat not operating
1: S3 is used
2: S4 is used
3: Both S3 and S4 are used

Alarm limits

The required temperature is indicated in °C.
The high-temperature limit will however be raised in the following situations:
- During night operation with the value "Dt Night K"
- If a signal is received from an override function via DANBUSS:
- the thermostat function will be overridden (peak load function)
- the alarm limit will be raised (extremely hot summerday)

Time delay

Three time delays are set for alarms:
For too high temperature:
High1Del m: Time delay after activation of the ON input,
time delay following defrost,
time delay after a power failure
The time delay will apply until the actual air temperature has dropped
below the "upper alarm limit".
High2Del m: Time delay during normal regulation
For too low temperature:
Low Del m: After the time delay the alarm will sound
The time delay is indicated in minutes:
Example
IN: Thermostat cut-in value
OUT: Thermostat cut-out value
Lim: Alarm limit for high temperature and low temperature
S: Alarm ceases
