SOM 9s
Display of collector temperatures
TCOL(1, 2)
Collector temperature
Display range: -40 ... +500 °F
Display of tank temperatures
Displays the current tank temperature.
• TSTB : Tank temperature bottom
• TSTT : Tank temperature top
in 2-tank systems (only if available):
• TST1T : Temperature tank 1 top
• TST1B : Temperature tank 1 bottom
• TST2T : Temperature tank 2 top
• TST2B : Temperature tank 2 bottom
TST (1, 2)B, TST (1)T
Tank temperatures
Display range : -40 ... +500 °F
note:
The values and adjustment channels shown
depend on the selected system, the functions
and options and will only be displayed in the
expert level. 6 Functions and options
6.1 Status level
Displays the current collector temperature.
• TCOL : Collector temperature (1-collector system)
• TCOL1 : Collector temperature 1 (2-collector system)
• TCOL2 : Collector temperature 2 (2-collector system)
Initialization
INIT
Initialization active
Filling time

Stabilization
Display of drainback time periods
Indicates the time adjusted in tDTO, running backwards.
Indicates the time adjusted in tFLL, running backwards.
Indicates the time adjusted in tSTB, running backwards.
Blocking protection
BLPR1(2, 3)
Blocking protection active
Display of blocking protection time
Display of temperatures at S3, S4 and S5
Indicates the current temperature at the corresponding
additional sensor (without control function).
• S3
: Temperature sensor 3
• S4 : Temperature sensor 4
• S5 : Temperature sensor 5
S3, S4, S5
Sensor temperatures
Display range : -40 ... +500 °F
note:
Only if temperature sensors are connected, will
S3, S4 and S5 be displayed.
note:
In systems with return preheating, S3/S5 is used
as the heat source sensor TSTR.
In order to protect the pumps against blocking after stand-
still, the controller is equipped with a blocking protection
function. This function switches on the relays every day at
12:00 a.m. for 10 s at 100%.
