PROGRAMMING

Entering Fan Program

The fan can be programmed to turn on at the beginning of a period and remain on through the whole period. In RunSched mode when the FAN switch indicates Prog Fan On the fan is programmed to be on for the period.

1)Press System button to select either Heat or Cool.

2)Press Menu button and then press Fan button to the right of the display.

3)The top of the display will show the day(s) being pro- grammed. The fi rst period to be programmed will appear.

4)Press the Fan button to change from Auto to Prog.

5)Press the Fan button to the right of the display to change to the next period.

6)Repeat steps 4 and 5 to program the fan for all periods of the day.

7)Press Fan to advance to the next day of the week and repeat steps 4 through 7 to program the fan for all days of the week.

Wired Remote Temperature Sensing

One remote temperature sensor can be installed indoor or outdoor and connected to the thermostat by a maximum cable length of 100 meters (300 feet). Terminals +, S and - on the terminal block allow connection of the remote sensor. The thermostat must have 24 VAC Common connection to terminal C for the remote sensor to operate. The remote sen- sor can be enabled or disabled in the Installer/Confi guration menu, item 16.

When remote sensor, Remote, is selected Off (factory de- fault), no remote sensor is enabled. When remote sensor is selected On, the next step is to select the remote as indoor, Remote In, or outdoor, Remote Outdoor. If the remote is se- lected as Remote In, an additional step will be to select if the temperature shown on the display will be from the thermostat, Loc On, or the remote sensor Loc Off.

In normal operation, when a remote sensor is enabled the time digits of the display will alternate between the time and the remote temperature for three seconds each. Above the remote temperature will be Remote, for indoor sensor or Outdoor Remote, for outdoor sensor. If the remote sensor is an indoor sensor and the local display has been disabled, the temperature displayed as the room temperature will be the remote sensor temperature.

Sensing Range:

Outdoor temperature range is -40oF to 140oF

Indoor temperature range is 32oF to 99 oF

Weighing of Remote Reading:

The thermostat will weight or average the temperature of the indoor remote sensor with the local sensor in the thermostat for each program period. The averaging will be active only when the local sensor and the indoor remote sensor are both functional and enabled in the Installer/Confi guration menu.

When the thermostat is in the Set Schedule mode, the weight of the indoor sensor will be shown in the current temperature digits of the display. The weight will show as A2 (average and

default), H4 (high) or L1 (low). Pressing the or but- tons at the same time will change the weight for the program period. The weight of the thermostat sensor is fi xed.

In normal operation of the thermostat, the current tempera- ture displayed will be the weighted average of the local sensor and the remote sensor using the formula (local sensor weight x local sensor temperature) + (remote sensor weight x remote sensor temperature) / (local sensor weight + remote sensor weight).

Example: Local sensor temperature is 80° and the remote sensor is 70°.

If weight is selected H4, the averaged temperature of 72° will be displayed.

(1 x 80) + (4 x 70) / 5 = 72°

If weight is selected A2, the average temperature of 73° will be displayed.

(1 x 80) + (2 x 70) / 3 = 73.3°

If weight is selected L1, the average temperature of 75° will be displayed.

(1 x 80) + (1 x 70) / 2 = 75°

The example shows that the weight selected would prioritize the overall averaged temperature between the two sensors. The high weight selection caused the remote sensor to have a higher infl uence in the calculated temperature average than the local sensor and the low weight selection caused the remote sensor to have less infl uence.
