Typical Connection of Triac Outputs 1 to 5

On the M2000 Rooftop controller, all triac outputs produce a 24 VAC live voltage when activated. Note
that all output voltages originate from a single voltage supply: the equipment's transformer. Consequen-
tially, only the live side of the output connections are usually needed; these are on the top row (see figure
15). The bottom row is the common (GND).

Typical Connection of Analog Outputs 1 to 3

For all analog outputs, the common is found on the bottom row terminal blocks, and the active signals
are found on the top row terminal blocks (see Figure 16). Analog outputs 1 can be configured to modulate
a 0-10 VDC load, to pulse a 0 or 10 VDC triac relay or to control a 10 VDC On/Off relay. Analog outputs 2
and 3 can only modulate a DC load (0-10 VDC or 2-10 VDC).
