HOLD − Using Temperature Hold Modes
PROG − Thermostat Programming
When HOLD is displayed at the HOME screen, the ther- mostat is in a temperature hold condition. This means that the temperature program data is ignored and the thermo- stat functions much like a non−programmable thermostat.
Adjusting Temperature Setpoint in Hold Mode
The temperature setpoint represents the desired tempera- ture of the space around the thermostat. The default tem- perature setpoint in Hold mode is 70°F.
To adjust the setpoint, press the UP or DOWN (YB) arrow buttons (see figure 12); the existing setpoint is displayed to the right of the actual room temperature. Each button press adjusts the setpoint up or down by 1 degree.

Permanent Hold Mode
At any time the program is running, from the HOME screen, set a permanent hold (program override) by press- ing the HOLD button (see figure 12). The thermostat now functions much like a non−programmable thermostat. Use the Up/Down arrow buttons to adjust the hold setpoint. To return to the program, press HOLD again.

While in Temporary Hold, press HOLD once to switch to Permanent Hold (HOLD displays solid; PROG not dis- played); press HOLD again to return to the program (PROG displays; HOLD not displayed).
The 51M37 thermostat can be programmed to perform a set of either heating or cooling events (but not a combination of heat and cool) for 5 consecutive days using a set of 4 unique events per day. The remaining 2 days can then be set for a different set of 4 unique events per day. Both the consecutive days and the events/temperature are set by the homeowner.
To Change Consecutive Days...
To alter the 5 consecutive days, press and hold the PROG button for 5 seconds. The 5 consecutive day period is then displayed (default is MOnday thru FRiday). To change to a different

To Set Program Events and Temperatures...
Figure 15 gives an example of how the two sets of pro- grams can be set for a normal workweek and weekend.
In the 5−day bar graph, note how programs A and C reflect the desired warmth while the home IS occupied (72°); B allows less heating while the home is NOT occupied; D re- flects a cooler sleeping temperature. The 2−day bar graph would support day−long occupancy and, because the first program begins later, a less−demanding time schedule.
