Installer setup (ISU) (continued)  
ISU Setup Number and Description  
Options (factory default in bold)  
0 °F to 5 °F  
0 °C to 2.5 °C  
Note: Differential is NOT deadband. Differential means  
how far past the setpoint before switching to the  
mode selected. Deadband setup is not an option. An  
advanced algorithm fixes the deadband at 0 °F. This is  
more advanced than previous thermostats.  
303 = Auto Changeover Differential  
0 = Comfort  
2 = 2 °F  
3 = 3 °F  
4 = 4 °F  
5 = 5 °F  
6 = 6 °F  
7 = 7 °F  
8 = 8 °F  
9 = 9 °F  
10 = 10 °F  
11 = 11 °F  
12 = 12 °F  
13 = 13 °F  
14 = 14 °F  
15 = 15 °F  
340 = Backup Heat Droop  
(PSTSN21AWH only)  
0 = Off  
5 = 90 minutes  
6 = 2 hours  
7 = 3 hours  
8 = 4 hours  
10 = 5 hours  
1 = 30 minutes  
2 = 45 minutes  
3 = 60 minutes  
4 = 75 minutes  
350 = Upstage Timer to Backup Heat  
(PSTSN21AWH only)  
1 - 6  
Note: This ISU is only displayed when Cool /  
Compressor Stage is set to 1 stage. Cycle rate limits  
the maximum number of times the system can cycle in  
a 1 hour period measured at a 50% load. For example,  
when set to 3 CPH, at a 50% load, the most the system  
will cycle is 3 times per hour (10 minutes on, 10 minutes  
off). The system cycles less often when load conditions  
are less than or greater than a 50% load.  
365 = Compressor Cycle Rate (Stage 1)  
1 - 12  
Note: This ISU is only displayed when Heat Stage is set  
to 1 stage. Cycle rate limits the maximum number of  
times the system can cycle in a 1 hour period measured  
at a 50% load. For example, when set to 3 CPH, at a  
50% load, the most the system will cycle is 3 times per  
hour (10 minutes on, 10 minutes off). The system cycles  
less often when load conditions are less than or greater  
than a 50% load. The recommended (default) cycle  
rate settings are below for each heating equipment  
type: Standard Efficiency Gas Forced Air = 5 CPH; High  
Efficiency Gas Forced Air = 3 CPH; Oil Forced Air = 5  
CPH; Electric Forced Air = 9 CPH; Fan Coil = 3 CPH; Hot  
Water Radiant Heat = 3 CPH; Steam = 1 CPH.  
370 = Heating Cycle Rate (Stage 1)  
375 = Heating Cycle Rate Auxiliary  
Heat (PSTSN21AWH only)  
1 - 12  
0 = Off  
1 - 5 minutes  
Note: The thermostat has a built in compressor  
protection (minimum off timer) that prevents  
the compressor from restarting too early after a  
shutdown. The minimum-off timer is activated after  
the compressor turns off. If there is a call during the  
minimum-off timer, the thermostat shows “Wait” in the  
display. This ISU is displayed if ISU 220 is set to at least  
1 stage.  
387 = Compressor Protection
