ID1-ID10, 10 inputs not optically isolated from power supply potential G0
powered at 24Vac current consumed by each input 6.5mA at 24Vac. The alarms
are active when the corresponding input is open (not powered). Input ID1,
for Remote ON/OFF, switches on the machine when powered. Input ID7, for
Cooling/heating, enables heating operation when powered.

maximum load 10mA 1K. Y2, 1 phase-cut output for Carel MCHRTF*0A0
regulator, impulsive at mains frequency, configured by user parameters for
pulse width modulation (PWM) or position, with loadless voltage of 4.8V ±10%
on minimum load of 1K.
oUt1-5, 5 SSR 24Vac 1A (optically isolated in three groups from G-Go) with
minimum current of 20mA. In addition, the 3 groups C1/2-OUT1-OUT2, C3/4-
OUT3-OUT4, C5-OUT5 are insulated from each other and this insulation is
functional (voltage < 50V). GND and G0 are connected internally. oUt6-c6,
