HOLD − Using Temperature Hold Modes
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 9); 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 9). 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.

PROG − Thermostat Programming
The 51M34 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 existing 5 consecutive day peri- od is then displayed (default is MOnday thru FRiday). To change to a different

To Set Program Events and Temperatures...
Figure 12 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 cool sleeping temperature. The 2−day bar graph would support day−long occupancy and, because the first program begins later, a less−demanding time schedule.
