MODBUS
FC013 Fancoil controller
Release 18.12.2014 ver. 01900
manual control
10 LSB
R, W RAM
manual output control and change-
over (C/O); if a bit is set to 1, the
output goes to state defined below
(see
manual fan speed, manual
heat output, manual cool
output, manual heat digital
output, manual cool digital
output
); if set to 0, PI controller
output values apply, and DO1 and
2 copy the AO1 and 2.
bit 0 ... AO3 - fan
bit 1 ... AO1 - heat output
bit 2 ... AO2 - cool output
bit 3 ... DO1 - heating
bit 4 ... DO2 - cooling
bit 5 ... C/O (1 = active)
