The end user can change the domestic hot water setting value.
The settings of the control of the actuator, tuning values and high
limit alarm settings can be found from the Service setting values
menu.
DHW Setting values
Domestic hot water setting
value 58.0 °C/
Send a message: DHW Settings.
The controller sends the domestic hot water temperature
setting to your mobile phone.
Editing the setting value: write the new setting in place of
the old setting and send a message back to the control-
ler. The controller sends the setting as a return message.

Range Explanation
Domestic hot water set-
ting value
58.0 0.0 ... 100.0 Because of the danger of bacteria, it is recommended that the domestic hot water
temperature is not permanently set below +55 °C.
Service setting values
The viewing and setting the Service setting values requires service code.
The Service setting values are such settings which are not typically
needed to be changed after H23 has been configured and taken in use.
--- ACTUATOR CONTROL ----
Actuator selection 3-point 3-point,
0(2)-10V,
10 - 0(2) V
Type of actuator.
Actuator running
time open
15 10...500 s The running time indicates how many seconds go by if the actuator runs a valve
nonstop from a closed position to an open position.
Actuator running
time close
15 10...500 s The running time indicates how many seconds go by if the actuator runs a valve
nonstop from an open position to a closed position.
Actuator oset 0 0...15 % The actuator dead zone. The controller starts to open the valve zero point
onwards.
--- TUNING VALUES----
P-area 70 2 ... 600 °C Supply water temperature change at which the actuator runs the
valve at 100%.
I-time 14 0 ... 300 s The deviation in the supply water temperature from the set value is corrected
by P amount in I time.
D-time
0 0 ... 10 s Regulation reaction speed up in the event of a temperature change. Beware of
constant waver!
Anticipation 120.0 1....250 °C Uses anticipation sensor measurement information to speed up regulation
when DHW consumption changes. Increase the anticipation value to de-
crease reaction to changes in consumption.
DHW Quick run 60 0 ... 100 % Functions during consumption changes. Decrease this value todecrease re-
action to quick temperature changes.
--- ALARM SETTINGS ---
Supply water high limit alarm
Alarm max limit 75 0...100 °C Supply water high limit alarm.
Alarm delay 10 0...120 min The high limit alarm is activated when the supply water temperature has ex-
ceed the high limit longer than the defined delay time.
