LOW VOLTAGE PEAK
CONTROL CONNECTIONS
If utilizing a Steffes Time Clock
Module or Power Line Carrier control,
refer to the installation instructions
provided with the device.
10
LOW VOLTAGE OUTDOOR SENSOR
CONNECTIONS
1. Route low voltage wire from load
control device to terminal block.
2. Connect field wiring to “RP” and “P”
positions.
The outdoor temperature sensor can be installed by wiring it directly to the
system or to the Steffes power line carrier (PLC) system.
Direct Wired:
1. Mount outdoor sensor in a location where it can accurately sense
outdoor temperature.
2. Route low voltage wire from outdoor sensor to electrical
compartment:
•
Outdoor sensor wire MUST NOT be combined with other control
wiring in a multi-conductor cable.
• Seal external wall openings.
• Outdoor sensor lead can be extended to 250 ft.
• Unshielded Class II (thermostat) wire can be used provided it is
segregated from any line voltage wiring.
3. Connect outdoor sensor wires to the two "OUTDOOR" positions of the
low voltage terminal block.
If connecting to the Steffes
power line carrier system,
follow the installation instruc-
tions in the PLC system’s
Owner’s and Installer’s Guide.
LOW VOLTAGE ROOM THERMOSTAT CONNECTIONS
A 24 VAC thermostat must be used (digital recommended).
1. Disconnect power to the Comfort Plus system.
2. Route low voltage wires from the thermostat to the
Comfort Plus System.
3. Insulate thermostat wire wall opening if necessary and
attach thermostat to the wall. When using a mechani-
cal thermostat or thermostat with anticipator, resistor
kit #1190015 must be installed to ensure proper
operation.
4. Connect low voltage wires from thermostat into
terminal block as shown.
