Automatic fan mode allows the equipment fan to run whenever there is a call for heating or cooling. Always On fan mode allows the fan to run continuously with or without a call for heating or cooling.
OVERRIDES
When the UT32 is configured for programmable operation, there are two types of temperature overrides available.
TEMPORARY TEMPERATURE OVERRIDE
Temporary Temperature Override is designed to allow you to adjust the heating or cooling temperature without affecting the programmed temperatures. For example, if you want to change the heating temperature, touch the display until the backlight comes on, and then touch the temperature setting. When Heat Set flashes, touch the UP or DOWN arrows to adjust the setting. The thermostat will resume normal operation in 10 seconds and display the new heating temperature. The program period (Morning, Day, Evening, Night) or (Day, Night) will flash continuously to provide confirmation that the temperature has been changed The new heating temperature will remain active until the next scheduled event takes place at which time it will be deleted and only the programmed temperatures will be used. To manually cancel Temporary Override, touch the display until the backlight comes on and then touch Program until Hold appears and then touch Hold. The thermostat will resume normal programmed operation and the override period will stop flashing.
PERMANENT HOLD
There may be times when a permanent override is required such as during a vacation or holiday period. To place the thermostat in Permanent Hold, touch the display until the backlight comes on and then touch Program until the word Hold appears. Next, touch the displayed temperature. While Set Heat or Set Cool are flashing, touch the UP or DOWN arrow to adjust the permanent hold temperature(s) that you want to maintain. Whenever you want the thermostat to resume normal programmed operation, touch the display until the backlight comes on and then touch Hold. The program will again appear and the thermostat will resume programmed operation.
OTHER OPTIONS AND FEATURES
ADAPTIVE RECOVERY OPTION
If your thermostat has been configured for programmable operation, your contractor can add the Adaptive Recovery Option. Adaptive Recovery compares the space temperature deviation from the set temperature for the next scheduled event and brings the equipment on to reach the next temperature setting at the scheduled event start time. Example: If you program a heating temperature to be 70 degrees at 6:00 PM, Adaptive Recovery will calculate when to bring the equipment on so that the temperature will be 70 degrees at 6:00 PM. The program period will flash during the Adaptive Recovery process. If the thermostat is placed in temporary temperature override, Adaptive Recovery is canceled for the next scheduled event.
CLEAN SCREEN
It is recommended that the touch screen be cleaned periodically. Use a slightly moistened clean, nonabrasive cloth. Touch the screen until the backlight comes on. Touch the Clean Screen window. All normal operating functions will be hidden and locked. The thermostat will count down from 30 seconds while you clean the screen. If more time is required, simply touch the Clean Screen box again.
COMPRESSOR TIME DELAY
Your thermostat has a built-in 4-minute time delay to prevent the air conditioner or heat pump from short cycling. When the short cycle timer is active and the thermostat is calling, the word Mode will flash on the display until the time delay has expired.
LOW BATTERY INDICATION
Your thermostat uses two AA batteries to keep the time-of-day clock running in case of a power failure. In some applications, battery power is also used to control the heating and air conditioning equipment. When the Low Battery icon appears on the screen, change the batteries immediately. If the battery power drops to a preset level, the backlight will be disabled and the display will only show the battery icon. All heating and cooling functions will be disabled and an audible beep will sound 3 times every 10 minutes between 7 am to 10 pm.
OUTDOOR TEMPERATURE DISPLAY
If an outdoor sensor has been installed on your thermostat, the outdoor temperature will be displayed from 1 degree Fahrenheit to 130 degrees Fahrenheit. If the outdoor temperature falls below 1 degree F, the thermostat will display LO and if the outdoor temperature rises above 130 degrees F, the thermostat will display HI.
CHANGING THE BATTERIES
Press in on the battery access compartment and slide the drawer out. Install two AA batteries matching the + (Positive) and – (Negative) orientations. Push the battery compartment in until it clicks shut. When the batteries are properly installed, the touchscreen display will resume normal operation with no loss of programming or current time.
TIMED VENTILATION OPTION
Your thermostat may have been set up to provide Timed Ventilation. Timed Ventilation is designed to improve residential indoor air quality by introducing fresh, outside air through a 2-wire, power-open / spring-closed motorized intake damper controlled by the thermostat. The thermostat automatically controls the amount of fresh air required each hour based on ASHRAE 62.2 – 2013 Ventilation and Indoor Air Quality Standard.
HOW IT WORKS
If your thermostat has been set up for Timed Ventilation, it will automatically open the outside air damper and turn on the system fan for a specific period of time each hour regardless of whether the thermostat is calling for heating or cooling. Whenever Timed Ventilation is active, the word FAN on the thermostat will flash. If an optional outdoor temperature sensor is wired to the thermostat, Timed Ventilation can be overridden by setting high and/or low outdoor temperature limits. If the outdoor temperature exceeds these limits the words Outdoor Air Temperature will flash and the outside air damper will remain closed and the system fan will not come on.www.iohvaccontrols.com For Technical Support Call Toll-Free: 866-225-5032
