GE Zoneline Built-in Electronic Temperature Limiting Feature
Temperature limiting gives you more control over operating costs of the GE Zoneline PTAC unit. By setting limits, no matter where the occupant sets the thermostat, the temperature limiting controls will determine the actual temperatures.
The GE Zoneline has the capability to set seven independent temperature limits for both heating and cooling. Independent, so there is no need to reset seasonally. To accomplish this, you will need to access the Auxiliary Control Switches. These are located behind the front cover, just below the control panel. There are two sets of auxiliary switches, 8 switches per set. We will be concerned with the second set, located on the right. The switches are number 1-8 from right to left. Switches 1-3 are the cooling limits, and work as follows:
Cooling Temperature Limits
| Switches Up |
None |
1 |
1,2 |
2 |
2,3 |
1,2,3 |
1,3 |
3 |
|
60 |
64 |
66 |
68 |
70 |
72 |
74 |
76 |
The heat limit switches are 4-6, and should be set as follows:
Heating Temperature Limits
| Switches Up |
6 |
4,6 |
4,5,6 |
5,6 |
5 |
4,5 |
