INSTALLATION
If the heating equipment manufacturer has made provisions or recommendations for the location of this control, then follow those instructions. If not, the following suggestions should be observed.
1.The control should be mounted in the wall, approximately five feet from the floor, as near as possible to the center of the controlled area.
2.It should be mounted on a partitioning wall, not on an outside wall.
3.It should be mounted as far as possible from undesirable sources of heat and cold such as:
a.Windows and doors
b.Direct rays from sun
c.Hot water or cold water pipes
d.Adjoining outside walls
WIRING
All wiring must conform to local and national electrical codes and ordinances.
The thermostat may be mounted in any standard 2" x 3" electrical outlet box. For ease of installation use a deep type box.
!CAUTION
USE WITH COPPER CONDUCTORS ONLY. Use ap- proved wire connectors for 12 AWG only.
1.Disconnect electrical power to the system at main fuse or circuit box.
2.Make electrical connection to thermostat leads with wire nuts or other local code approved devices. All connections must be tight.
3.Push the lead wires into the outlet box.

Temperature Limiting Pins
Temperature Limiting Option is for applications where the temperature setting of the control is to be set and "protected" from unauthorized adjustment. To limit the temperature range, follow the directions below:
1.Remove cover from thermostat.
2.On inside of cover, firmly press small tapered end of a pin into the approximate maximum and minimum temperature positions.
3.After pressing pins into place on inside of cover, rotate temperature knob to be sure the knob is between the pins.
4.Replace cover on thermostat. Check that knob rotation is limited in travel as set by the pins. If rotation of knob is outside of limits, check that the pins are installed properly.
5.Install supplied screws at top and bottom of thermostat to secure cover.
Inside of cover
Pins are shown installed at 60 and 65˚. The temperature setting range is limited between these two temperatures.
The third pin is supplied as a spare in case of accidental loss.
