Wiring Method

NOTE: When attaching two or more wires to the same
terminal, 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. 17). 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. 17).
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 10 are
shown in Fig. 19 and Fig. 20 on page 20 and 20.

Analog outputs may be configured as digital outputs and operate as
follows:
– False (0%) produces 0 Vdc, (0 mA)
– True (100%) produces the maximum 11 Vdc (22 mA)
