Typical Connection of Triac Outputs 1 to 5

On the M2000 Boiler 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. Consequentially, only the live side of the
output connections are usually needed; these are on the top row (see Figure 12). The bottom row is the common (GND).
Typical Connection of Analog Outputs 1 to 3v
For all analog outputs, the common is found on the bottom row terminal block, and the active signals are found on the
top row terminal block (see Figure 13). Analog output 1 is configured to control a 10 VDC On/Off relay. Analog outputs 2
and 3 can only modulate a DC load (0-10 VDC, 2-10 VDC, 0-5 VDC).
