be reset by INIT nor by any other
means
relay
7 LSB
R, RAM
output relay status (DO1-DO2) -
copy of the AO1 and AO2 outputs
bit 0 ... relay 1, heating
bit 1 ... relay 2, cooling
inputs
7 MSB
R, RAM
digital input status (DI1 ...
presence, DI2 ... window / alarm
contact). The DI status respects
the NO/NC settings in
inputs
settings
register. Slave controllers
are taken into account if the inputs
are enabled for controls at the
master module.
bit 0 ... input(s) DI1
bit 1 ... input(s) DI2
bit 2 ... heating demand
(PID output HEAT > 5%)
bit 3 ... cooling demand
(PID output COOL > 5%)
