3° F Both This ISU is only displayed when ISU 300 is set to

Deadband is the minimum separation between heat and cool settings when the thermostat is setup for Auto Changeover. For example, if the deadband is set to 3° F and the cool setpoint is 75° F, the warmest heat setpoint allowed would be 72° F. If the heat setpoint is adjusted above 72° F, it will automatically adjust the cooling setpoint higher to maintain the 3° F deadband.
When ISU 907 or ISU 910 (Dehum Over Cooling Limit) is set to 1, 2, 3, 4 or 5 F, the thermostat will not show the full Deadband range. For example, if you set a Deadband of 3 F and an Over Cooling Limit of 2 F, the minimum Deadband that you can select will be 5 F. This prevents the heating system from turning on when the thermostat over cools to reach the dehumidification setting.

Lockouts Residential Lockouts are Priority: The thermostat places a
priority on lockouts versus the ASHRAE 62.2 ventilation standard. The thermostat will not run ventilation during the following lockout conditions (if configured) unless you manually call for ventilation:
Lockout Ventilation during Outdoor Conditions (ISU 1013)
Lockout Ventilation on Humidification or
Dehumidification Calls (ISU 1014)
Lockout Ventilation during “Sleep” (Residential)
or “Unoccupied” (Commercial) program periods. Note: This option is set by the user on the Ventilation screen in the Menu.
ASHRAE is Priority: ASHRAE requires additional ventilation following a long off cycle. The thermostat meets the ASHRAE 62.2 ventilation standard by running additional ventilation when outdoor conditions are favorable. If ASHRAE cannot be met when outdoor conditions are favorable, the thermostat will override the outdoor lockouts and run ventilation. When using this option, it is recommended to increase the rate (CFM) of the ventilation equipment to meet the ASHRAE 62.2 ventilation standard in a shorter run time.

Advanced Features

ADAPTIVE INTELLIGENT RECOVERY (RESIDENTIAL USE ONLY)
Over time, the VisionPRO® thermostat "learns" how long it takes your system to reach your programmed temperature setting.
The thermostat turns on the heating/cooling system early and assures that the programmed temperature setting is reached at the programmed time regardless of weather conditions. For example, if the Wake program period is set to 6:00 am with a heat setting of 70 degrees, the heat will turn on before 6:00 am, so the temperature is 70 degrees at 6:00 am. The thermostat displays "In Recovery" when it turns the system on early.
Adaptive Intelligent Recovery® calculates the recovery ramp based on how far the room temperature is away from the temperature setting, previous equipment performance and weather history, allowing the thermostat to start recovery at the optimal time so it can reach the programmed temperature setting at the programmed time.
The VisionPRO® thermostat uses two recovery ramps when setup to control a heat pump system. One ramp for the compressor and one ramp for the auxiliary heat. Once the room temperature intersects the compressor ramp, the compressor turns on until the setpoint is reached. If the room temperature does not rise quickly enough and intersects the second ramp, the auxiliary heat turns on. It takes about one week for the thermostat to adjust to weather conditions, equipment performance and construction of the home. If the temperature setting is reached too early or too late, the ramp is adjusted for the next day's recovery. See Fig. 96.
P + I CONTROL
A conventional mechanical or electronic thermostat does not control temperature precisely at setpoint. Typically there is an offset (droop) in the control point as the system load changes. Many factors contribute to offset including the switch differential, thermal lag, overshoot, cycle rates and system load.
The VisionPRO® thermostat however, works much differently than a conventional mechanical or electronic thermostat. The proprietary algorithm in the thermostat eliminates the factors causing offset (droop). This makes temperature control more accurate than the conventional mechanical or electronic thermostat. The temperature control algorithm is called proportional plus integral (P + I) control.
The thermostat sensor or indoor sensor senses the current space temperature. The proportional error is calculated by comparing the sensed temperature to the setpoint temperature. The deviation from the setpoint is the proportional error.
The thermostat also determines integral error, which is a deviation based on the length of error time (how long the sensed room temperature has been away from the setpoint temperature). The sum of the two errors is the (P + I) error. The cycle rate used to reach and maintain the setpoint temperature is computed using the P + I control algorithm. The addition of the integral error is what differentiates the thermostat from many other mechanical and electronic thermostats. See Fig. 97.

Your system can be set to control indoor climate while your home is vacant during the humid season. Before you leave, touch MENU, then select Dehum Away Mode. Temperature and humidity will be kept at levels that protect your home and possessions. When you return, touch Cancel to resume normal operation.
COMPRESSOR PROTECTION
The thermostat keeps the compressor off for a few minutes before restarting, to prevent equipment damage. During this "off" time, the message "Wait" is displayed on screen.

The U1 contacts can be setup to control IAQ equipment or a stage of heating or cooling in the Installer Setup. Setup options are listed below.
33-00096—05 52
Heat Differential
The indoor temperature must drop to the selected differential setting before the thermostat will turn on the stage of heating. For example, if stage 2 is set to 2 °F (1.0 °C), the indoor temperature must be 2 °F (1.0 °C) away from the setpoint before stage 2 turns on. When set to Comfort, the thermostat will use the stage of heating as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the setpoint. The thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.
Cool Differential
The indoor temperature must rise to the selected differential setting before the thermostat turns on the stage of cooling. For example, if stage 2 is set to 2 °F (1.0 °C), the indoor temperature must be 2 °F (1.0 °C) away from the setpoint before stage 2 turns on. When set to Comfort, the thermostat uses the stage of cooling as needed to keep the indoor temperature within 1 °F (0.5 °C) degree of the setpoint. The thermostat turns on stage 2 when the capacity on stage 1 reaches 90%.

Backup Heat Droop
A Backup Heat Droop is available for any system with 2 heating types. For example:
• Heat Pumps with any type of Backup Heat
• Radiant Heat with any type of Backup Heat
• Hot Water Fan Coil with any type of Backup Heat
The Backup Heat Droop restricts backup heat during the following conditions:
•Normal Operation
• Manual Setpoint Changes
When the Backup Heat Droop is set to 2 °F or higher, backup heat is not used unless the indoor temperature drops to the Backup Heat Droop setting or the Backup Heat Upstage Timer expires, whichever occurs first. The upstage timer starts when the highest stage of the previous equipment type turns on.
MANUAL TEMPERATURE CHANGE
When the Backup Heat Droop is set to Comfort, the thermostat uses backup heat as needed to keep the indoor temperature within 1 °F (0.5 °C) of the setpoint. The Comfort setting is NOT an option on heat pumps with fossil fuel backup heat.
When the Backup Heat Droop is set to 2 °F or higher, if the primary heat is making progress as expected, backup heat will not be used to reach the new setpoint. Set to a higher number to use less backup heat (a greater difference between the current indoor temperature and the new setpoint is required to turn on backup heat). See notes below.
PROGRAMMED RECOVERY
If the primary heat is making progress as expected, backup heat will not be used to reach the setpoint of the next program period. Backup heat is always restricted during a programmed recovery when the Adaptive Intelligent Recovery feature is used. See note below.
NOTE: During a programmed recovery (or when the tem-
perature setpoint is changed by the user), the thermostat waits to turn on the backup heat depending on system performance, load condi­tions and how many degrees the temperature set­point is changed. Backup heat will be used ONLY when the temperature is not rising quickly enough to reach the setpoint in a reasonable time.
NOTE: If the backup heat was used in the last 2 hours
because the primary heat was not able to maintain the setpoint, the thermostat may turn on the backup heat earlier when the user raises the set­point. This does NOT apply to heat pumps with fossil fuel backup heat.
TO CHANGE BACKUP HEAT DROOP SETTINGS
1. Select Basic Options or Advanced Options to
view/adjust Backup Heat Droop settings.
The options are:
• Comfort – keeps temperature within 1 degree of the setpoint.
• 2 to 15 °F – Backup heat is not used unless the indoor temperature drops to the selected Backup Heat Droop. For example, if the Backup Heat Droop is set to 2 °F (1.0 °C), the indoor temperature must be 2 °F (1.0 °C) away from the setpoint before the backup heat turns on.
NORMAL OPERATION
When the Backup Heat Droop is set to Comfort, the thermostat uses backup heat as needed to keep the indoor temperature within 1 °F (0.5 °C) of the setpoint. The Comfort setting is NOT an option on heat pumps with fossil fuel backup heat.

INDOOR AIR QUALITY (IAQ) CONTROL

Humidification

The thermostat reads the indoor humidity level and allows the user to set a humidification setting with or without window protection.
The thermostat can be set up to control a humidifier in any system mode in the Installer Setup (ISU 806). A discharge air sensor is required to humidify in the cool mode.
If humidification and dehumidification are setup to operate in the same system mode (Heat, Cool, Off) the thermostat will automatically enforce a 15% deadband between the humidification and dehumidification settings. The thermostat will automatically switch between humidification and dehumidification to maintain the desired humidity level.
Window Protection
Window Protection limits the amount of humidity to prevent frost or condensation on windows. Window Protection (ISU 805) requires an outdoor sensor.
your windows during cold outdoor temperatures, poorly insulated windows require a lower Window Protection setting, which will limit how much your humidifier can run.
After you set the Window Protection setting, check for frost/condensation on your windows in the morning. If frost/condensation is present, adjust the Window Protection setting to the next lowest number and check for frost/condensation on your windows the next morning. Continue to adjust the Window Protection setting to a lower number until frost/condensation is no longer present.
Fig. 114.
If Window Protection is turned Off, the thermostat controls the humidity level to the user's desired humidity setting. Frost or condensation may appear on windows.
Set up Humidification
1. Select the Humidifier Type at ISU 800. See Fig. 115.
NOTE: Based on the humidifier type you select, the
thermostat defaults to the most commonly used settings for that humidifier type. For example, a Bypass or Fan Powered humidifier will default ISU 807 to “Hum when Heat is On.” A Steam humidifier will default ISU 807 to "Tstat Controls Fan."
The thermostat prevents frost or condensation on windows by not allowing the humidifier to run above a certain level. To prevent frost or condensation, the thermostat may turn off the humidifier before the humidity setting is reached.
To adjust the Window Protection setting, press MENU, scroll down and select Window Protection. Window Protection is set on a scale from 1-10. A setting of "1" represents poorly insulated windows and a setting of "10" represents well insulated windows. A lower number automatically reduces the humidity to help prevent frost or condensation on your windows. Use a higher number if indoor air seems too dry. To prevent frost/condensation on

Dehumidification Equipment Options: (ISU 900)
• A/C with Low Fan
• A/C with High Fan
• Hot Gas Bypass
• Dehumidifier
NOTE: Hot Gas Bypass - During a call for dehumidifica-
tion, the cooling capacity will be used to remove more latent heat than sensible heat. The operation of Hot Gas Bypass varies by equipment. For more details, contact the equipment manufacturer.
Dehumidification using the Cooling System
Dehumidification using A/C with Low Speed Fan, A/C with High Speed Fan or Hot Gas Bypass, has the following methods of dehumidification control (ISU 908):
heating coil (heat exchanger). This feature requires a conventional forced air heating system (gas, oil, or electric) in the application.
NOTE: Reheat can be used on heat pump applications
that have a forced air backup heat source (gas, oil, or electric). The thermostat will turn on the first stage of forced air backup heat during Reheat.
NOTE: Reheat can be used on systems where the A-Coil is
located after the heating coil (heat exchanger), but it is not effective at removing humidity.
Reheat with Minimum On Time (ISU 908 and 909): This method uses both Reheat and Minimum On Time options above to reach the desired humidity level.
If set for A/C with Low Speed Fan, configure U1 as normally open or normally closed (ISU 905) and wire to the Low Speed Fan terminal on the equipment. For example, if the U1 terminal is normally closed, it will open when the thermostat calls for dehumidification.
NOTE: The thermostat will not lower the fan speed when
the second stage of cooling is on.
Set up Dehumidification With Cooling System
Some screens shown in this section may not appear on the thermostat, depending on how you set up dehumidification.
Fig. 144.
Basic (ISU 908): This option uses the cooling system to reach the desired humidity level. Minimum On Time, Cooling Droop and Reheat are not used with this method. This setting is commonly used if your dehumidification equipment is Hot Gas Bypass.
Minimum On Time (ISU 908 and 909): This option ensures that the compressor runs long enough to effectively reduce humidity when the cooling equipment is cycled on. The compressor will run for the minimum “on time” you set until the desired humidity level is reached.
Cooling Droop (ISU 908 and 910): This option uses the cooling system to lower the temperature up to 5° F below the current cool setpoint until the desired humidity is reached. The Dehum Over Cooling Limit range is from 1° to 5° F.
Cooling Droop with Minimum On Time (ISU 908, 909, and
910): This method uses both options above to reduce humidity while maintaining a comfortable temperature.
Reheat (ISU 908): This option allows heating to run during dehumidification to help maintain a comfortable temperature. If only cooling stage 1 is used, during the “off” cycle, both cooling and heating run at the same time as needed to dehumidify without overcooling. This option cannot be used in the Heat mode. This option is effective only if using a system with the A-Coil located before the

Ramp Rates (Commercial Use)

When the ramp rate is set to Off, the thermostat begins recovery at the scheduled time.
When a ramp rate is set, recovery begins early to reach the setpoint by the program time. Based on your recovery ramp setting and how far the thermostat is set back, the thermostat determines how early to turn on the system.
If an outdoor sensor is installed, you can set outdoor temperatures for mild, cold and hot days in your region. By setting these outdoor temperatures, the thermostat will automatically adjust the ramp rate based on outdoor conditions. This allows the thermostat to save energy by starting recovery at the optimum time as outdoor conditions change.
NOTE: The thermostat uses an adjustable ramp rate
when the thermostat is setup for commercial. This allows the thermostat to recover on time during changing conditions (occupancy changes, tem­perature overrides, load conditions, opening/clos­ing of doors etc) which are common in commercial applications.
Fig. 216.
Fig. 217.

Economizer and Time of Day (TOD) Operation

Economizer
The thermostat controls an economizer module to provide ventilation during occupied periods and free cooling when outdoor conditions are favorable. In some climates the cooling system may run several hours when it may not be required to maintain indoor comfort. When outdoor conditions are favorable, ventilation with outdoor air can achieve the same level of comfort at lower cost. Table 5 explains how the Economizer Module is controlled by the thermostat.
The thermostat works with the W7220, W7212, W7213 and W7214 Economizer Modules for both heat pump and conventional systems.

WIRED INDOOR SENSORS

For wiring, see “Wiring guide — Wired Indoor Sensors” on page 89.

Indoor Sensor Operation

Temperature Control
The thermostat can be set to respond to its internal temperature sensor, or to an optional wired indoor sensor. If multiple sensors are used, the thermostat will average the temperature detected at each sensor.
Fig. 218.

Pre-Occupancy Purge

The thermostat can be set up for Pre-Occupancy Purge in the installer setup (ISU 401). When setup for Pre­Occupancy Purge, the thermostat runs the fan 1 to 3 hours before each occupied period to provide a comfortable workplace upon arrival. Options are Off and 1 to 3 hours.
In Fig. 220, both the thermostat internal sensor and wired indoor sensor are being used for Temperature Control and are being averaged since both sensors are set to “Yes.” Select “No” if you do NOT want a specific sensor to be used for temperature control or be part of the temperature average.

* Remove factory installed jumper for two transformer systems.
The THP9045A1098 C-wire adapter is used on heat/cool systems when you only have four wires at the thermostat and you would like the thermostat to be powered with a common wire. Use the K terminal in place of the Y and G terminals on conventional or heat pump systems to provide control of the fan and the compressor through a single wire—the unused wire then becomes your common wire. See page 85 and the THP9045 instructions (form 33-00342) for more information.

Wiring with the THP9045 C-Wire Adapter

The THP9045 C-wire adapter is designed to be used with applicable thermostats in which a 24V common is required and there are not enough wires. The K terminal on the thermostat can be used to operate both the fan and compressor on a single wire, and the module is designed to receive the signal from the K terminal, split that signal and re-route it to operate the compressor and/or fan for normal operation. See form 33-00342 for additional information.
