IMPORTANT PREMISES
When an external regulator with 0÷10 V signal for heat output control is used, the system must feature, on device flow, an
additional temperature probe connected to the external regulator.
IF it is not present, this must be installed.
DEViCE sETTiNGs
With these settings, the device heat output / temperature is managed directly via the 0÷10 V signal, as follows:
- Access the Technical menu (see page 34)
- Access “1. CH” and proceed to line "6. Request type" (see page 35)
- Then select “0-10 V [%] signal” (request for heat output control) or “0-10 V [sP] signal” (request for temperature control).
A) with increasing voltage voltage < 2 V
---> OFF
2 V ≤ voltage ≤ 10 V ---> linear variation of Heat output or Temperature
B) with decreasingvoltage 2 V ≤ voltage ≤ 10 V ---> linear variation of Heat output or Temperature
1 V ≤ voltage < 2 V
---> Minimum heat output or Minimum Temperature
voltage < 1 V
---> OFF
in both modes the climate control is managed by the external regulator, therefore, at least one of the following conditions must
be met to prevent any overlaying of time slots:
- Timer disabled
- Timer enabled but in “OFF” mode
To change the functions at level “3.Timer Setting”:
- Access the Engineer Menu (see page 34)
- select “5. UsER sETTiNGs” (see page 37)
- Access line “1.Ch” and move to line “3.Timer Setting”
IMPORTANT
The heating function (CH) must always be active (not disabled).
