Wiring Method
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring, or
making wiring connections, to prevent electrical shock
or equipment damage.
NOTE: When attaching two or more wires to the same termi-
nal, other than 14 AWG (2.0 sq mm), be sure to twist
them together. Deviation from this rule can result in
improper electrical contact (see Fig. 15).
Each terminal can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded, with 1/4 watt
wire-wound resistor
Prepare wiring for the terminal blocks, as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in the
required terminal location and tighten the screw.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them (see Fig. 15).
4. Cut the twisted end of the wires to 3/16 in. (5 mm) before
inserting them into the terminal and tightening the screw.
5. Pull on each wire in all terminals to check for good
mechanical connection.

Wiring Details
Each controller is shipped with the digital outputs, which switch
the 24 Vac to the load (High Side).
The three analog outputs (AO) are used to control modulating
heating, cooling and economizer equipment. Any AO may be
used as a digital output, as follows:
— False (0%) produces 0 Vdc, (0 mA)
— True (100%) produces the maximum 11 Vdc (22 mA)
The wiring connection terminals described in Table 6 and 7 are
shown in Fig. 16 and Fig. 17 starting on page 14.
