3. For 24V power supply a J2 type connector is supplied. Install
J2 connector as shown. Remove J4 connector if necessary.
See Figure 4.
NOTE: If rewiring of connectors is required, see Figure 5 or 6
for wire control power supply terminals. J2 connector is
for 24V AC/DC, 100 mA and J4 connector is for 120V or
240V, 100 mA. Use only 18–26 AWG copper wire rated
for 90°C for connections.
CAUTION
CAUTION. All circuits must have a common disconnect
and be connected to the same pole of the disconnect.
Electrical ratings stated must not be exceeded.
Step 1
Mount thermostat approximately 5' (1.5 m) above the floor where
average room temperature will be sensed and air circulates freely.
Keep thermostat away from hot and cold surfaces.
Step 2
1. Three types of power supply terminals are supplied. Installed
on the thermostat is a J4 connector wired for 120V. See
Figure 1.
2. A J4 connector is supplied seperately for 240V power supply.
Simply remove 120V J4 connector and install 240V J4
connector. See Figure 2 and 3.

Step 6
Rotate the adjustment knob until the desired set temperature is
displayed by the indicator. See Figure 11.
Step 7
Periodically ensure all field wiring connections are secure and
undamaged.
CAUTION
CAUTION. The thermostat must not be modified in
any way. It is factory calibrated and cannot be
recalibrated in the field.
Step 3
Wire load switch relay as per Figure 7 for resistive heating load
and Figure 8 for pilot duty load. Use correct rated wire depending
on voltage used. Use copper wire rated for 90°C connections.
For heating applications, attach wire to N.O. terminal. See Figure 9.
For cooling applications attach wire to N.C. terminal. See Figure 10.
Step 4
Install the cover using the 4 bolts supplied and tighten.
Step 5
Fill any unused conduit opening using plug supplied.

Subject to State or Provincial law to the contrary, the Company
will not be responsible for any expense for installation, removal
from service, transportation, or damages of any type whatsoever,

responsibility of the user.
This warranty will be void if, in the judgment of the Company, the
damage, failure or defect is the result of:
• Vibration, radiation, erosion, corrosion, process con-
tamination, abnormal process conditions, temperature and
pressures, unusual surges or pulsation, fouling, ordinary
wear and tear, lack of maintenance, incorrectly applied
utilities such as voltage, air, gas, water, and others or any
combination of the aforementioned causes not specifically
allowed for in the design conditions, or
• Any act or omission by the Purchaser, its agents, servants
or independent contractors which for greater certainty, but
not so as to limit the generality of the foregoing, includes
physical, chemical or mechanical abuse, accident,
improper installation of the product, improper storage
and handling of the product, improper application or the
misalignment of parts.
No warranty applies to paint finishes except for manufacturing
defects apparent within 30 days from the date of installation.
The Company neither assumes nor authorizes any person to assume for it
