- S26 (5) can only be modified if the Super C.A.R. remote control
can be coupled with the Superior kW range boilers.
- S26 (6) in the event of the setting with max. flow temperature of
75°C, the relative safety thermostat must be replaced with one
suitable for supporting this temperature.
Warnings.
Various LEDs are present on the board to display the
functioning status and to indicate any anomalies.
The LEDs from 1 to 7 (1 Fig. 38) identify the activation of the
relative relay:
- LED H1 zone 1 activation (high temperature)
- LED H2 zone 2 activation (low temperature)
- LED H3 zone 3 activation (optional)
- LED H4 mixed zone 2 mixer opening
- LED H5 mixed zone 2 mixer closure
- LED H6 mixer opening zone 3 (optional)
- LED H7 mixer closing zone 3 (optional)
The LED H11 signals that the zone management board is powered.
LEDs 8 and 9 indicate the functioning status of the board:
