10.3.7 Setting D.H.W. temperature
Setting mode, step 3.
Setting this value is only important if a remeha D.H.W.
sensor is used.
The basic setting is: D.H.W. operation with a D.H.W. tem-
perature of 65°C.
To make alterations, see para. 6.4.1 and 6.4.10.
10.3.8 Switching D.H.W. operation on and off
Setting mode, step A.
The basic setting is: boiler operation on. To switch off the
D.H.W. function, you should carry out the actions below:
- Using the 'mode' key, go to setting mode (the dot in
the 'code' display will light up continuously).
⇑
- Press the 'step' key until the letter A. appears in the
'code' display.
⇑
- Change the setting using the ' ' and ' ' keys:
Code Description ('X' = don't care)
A. 1 X central heating modulating
2 X central heating high/low ext. input
X 0 central heating off, D.H.W. off
X 1 central heating on, D.H.W. on
X 2 central heating on, D.H.W. off
X 3 central heating off, D.H.W. on
- Store the new setting in the memory by pressing the
'store' key. The temperature window will flash as a
sign that the value has been stored.

- Press the 'reset' key to return to operating mode.
Note:
In the factory, the control has been set so that the appli-
ance will switch off if the measured D.H.W. temperature
is 5°C (preset value) above the preset boiler tempera-
ture. The appliance switches back on at a temperature
5°C below the shutoff point, i.e. at the boiler tempera-
ture set by yourself. This cut-in temperature differential
can be adjusted to a maximum of 20°C. To alter this
value, follow the instructions in par. 10.3.9.
If you do not wish to change the value, installation is
now finished.
10.3.9 Changing D.H.W. operating cut-in tempera-
ture differential (service level)
Setting mode, step b.
Preset 5˚C.
Change setting: see para. 6.4.1 and 6.4.3.
Note:
When using a D.H.W. thermostat, the value of the cut-in
differential is used as a switch differential for flow tem-
perature in the event of an appliance control stop in
D.H.W. operation.
10.3.10 Changing maximum flow temperature
during D.H.W. operation
(service level)
Setting mode, step I.
Preset 80˚C.
Change setting: see para. 6.4.1 and 6.4.3.
10.3.11 Changing three-way valve/boiler pump
setting
(service level)
Setting mode, step J.
Preset three-way valve.
Change setting: see para. 6.4.1 and 6.4.3.
