), press the ' # ' key prior to entering the temperature to make the number negative. A
Celsius temperature may also be specified in 0.5 degree steps if three numeric digits are entered. The third digit adds a .5 to the
first two digits if it is any- thing other than zero. Enter a leading zero if necessary.
Temperature Control of Appliances
You can control appliances (such as a ceiling fan) using Advanced Control Programming (ACP) of the Omni IIe. For example,
the ceiling fan can be programmed to come on if the temperature goes above the High temperature.
High and Low setpoints for temperature zones are changed the same way as the PESM. However, on/off control of the ceiling
fan is done from the 1 (CONTROL) menu. Use the ceiling fan's unit number to turn it On or Off. The PESM or Model 31A00
Temperature Sensor and the ceiling fan are linked together by an event button program.
Temperature Alarms
Temperature sensors can be used to signal that a temperature (in a special room, like a greenhouse or wine cooler) has gotten too
high or too low. If the temperature in this zone goes above the High setpoint or below the Low setpoint, the console beeper is
activated (inside and outside sirens are not activated) and the central station and/or voice dialer is called.
The High and Low setpoints are changed as described for the PESM. Use the zone number that the temperature sensor is
connected to in place of the unit number.
NOTE: Setting a High or Low temperature to 0 takes it out of service.
Humidity
The Model 31A00-2 and 31A00-8 Indoor/Outdoor Temperature and Humidity Sensor is used for sensing indoors temperature
and/or reporting the relative humidity from 0 to 100 percent or for sensing the outdoor temperature and/or reporting the outdoor
relative humidity.
High and low humidity limits can be set for taking action (i.e. turning on the bathroom vent fan, running a/c in de-humidification
mode, turning on humidifier in heating mode, etc.) or reporting high or low humidity conditions in homes, greenhouses, wine
cellars, coolers, humidors, etc. Controlling humidity is particularly helpful in combating the growth of mold in vulnerable areas
of the home, such as bathrooms, basements, attics, etc.
The humidity level (0-100%), the low humidity setting, and high humidity setting can be viewed and modified using the
temperature menu. To enter the temperature menu, from the top-level display or from the main menu, press the 5 (TEMP) key.
The humidity zone can be specified by entering the zone number followed by the ' # ' key, or by pressing the arrow keys to scroll
through the list of temperature and humidity zones. Press the ' # ' key when the desired temperature zone is shown.
INDOOR: HUMI: 75
