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

to Automatic.

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.

Initiate Occupancy: The system maintains temperature at an energy saving level until the user touches the message center area on the thermostat. Note: The message center displays Press HERE to Start Occupancy. The system will then maintain a comfortable temperature until the occupied period ends. This option is recommended for cost savings when the workplace is used infrequently or arrival times change from day to day (example - schools). After the user touches Press HERE to Start Occupancy, the user will still be able to perform a standard OVERRIDE of the schedule.

Lockouts ASHRAE

Residential, Commercial

or Both Notes

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.

Staging Control

Differential Between All Stages

The thermostat provides Differential settings between all stages. The equipment changes stages based on how far the indoor temperature is from the setpoint. Differential settings provide a way to balance comfort and conservation.

Universal Output (U1, U1)

The U1 universal output can be setup to control IAQ equipment and a stage of heating or cooling in the Installer Setup. Setup options are listed below.

MCR33985

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

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 Backup Heat Droop restricts backup heat during the following conditions:

• Normal Operation

• Manual Setpoint Changes

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 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.

HEAT PUMP AND BACKUP HEAT OPERATION

Heat pump with outdoor temperature lockouts

Outdoor temperature lockouts are optional. See Installer Setup options (ISU 312).

Alert Light - General

An alert light is located in the lower right corner of the thermostat. See Fig. 28 and 29. This light turns red when an alert is active or the system is set to the Em. Heat mode.

Alert Light - Heat Pump Systems

When the L terminal is wired to a compressor monitor and it receives 24 volts, the alert light on the thermostat will turn red to indicate a system problem. The thermostat monitors 24 volts on the L terminal in Heat, Cool and Auto modes.

Alert Light - Emergency Heat Indication

When the thermostat is setup for a Heat Pump with an Auxiliary Heat source, the alert light will turn red when the user sets the system to the Em. Heat mode. It is normal for the alert light to turn red in the Em. Heat mode to remind the user that they are currently operating their Emergency Heat and the Heat Pump is locked out.

Geothermal Radiant Heat

The thermostat can be setup to control Geothermal Radiant Heat, Geothermal Forced Air Heat and Backup Heat, all from one thermostat. The thermostat stages the equipment starting with the Geothermal Radiant Heat followed by Geothermal

Forced Air Heat and then Backup Heat as needed to maintain the desired temperature. The thermostat allows you to set differential temperature settings between each stage if you want the equipment to stage a certain way (see ISU 303 to ISU 309, page 16). For additional wiring diagrams, see “Wiring” beginning on page 84.

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) and you are sensing humidity from one location, 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.

If humidification and dehumidification are setup to operate in the same system mode (Heat, Cool, Off) and you are sensing humidity from two different locations using a indoor sensor, the thermostat will allow humidification and dehumidification to operate at the same time, and there is no deadband between humidification and dehumidification settings.

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 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."

Window Protection

Window Protection limits the amount of humidity to prevent frost or condensation on windows. Window Protection (ISU

805) requires an outdoor sensor.

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

Dehumidification - Residential

The thermostat reads the indoor humidity level and allows the user to set a dehumidification setting. The thermostat controls the humidity level using the cooling system or a whole house dehumidifier.

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.

Dehumidification using the Cooling System

When set for A/C with Low Speed Fan or A/C with High Speed Fan, an overcooling limit can be set from 0 °F to 3 °F (ISU

907). The thermostat uses the cooling system to reduce humidity by lowering the temperature up to 3° F below the current cool setpoint until the desired humidity level is reached.

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.

• 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):

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.

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.

1. Select the Dehumidification Equipment in ISU 900. See Fig. 145.

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 ACoil located before the heating coil (heat exchanger). This feature requires a conventional forced air heating system (gas, oil, or electric) in the application.

Ventilation

The thermostat can be set for the following ventilation types: (ISU 1000)

•ERV/HRV

• Passive (Fan Only)

• Fresh Air Damper

Ventilation Control Methods (ISU 1005)

Ventilation can be setup to meet either ASHRAE or Percent On Time settings. To meet these settings, the thermostat will ventilate during calls for heat, cool, and fan. If the required ventilation has not been achieved for ASHRAE or Percent On Time, the thermostat will force the ventilation equipment on.

• ASHRAE The thermostat operates ventilation equipment to meet the ASHRAE 62.2 ventilation standard based on CFM, number of bedrooms, and square footage of the house. ASHRAE

62.2 can only be met if the ventilation equipment is running. If the ventilation equipment is off for any reason (outdoor ventilation lockouts, set up to turn Off during Sleep period, turned off by user, etc.), ASHRAE 62.2 is not met during those times. See ISU 1012 to select a Ventilation Priority.

• Percent On Time The thermostat operates ventilation equipment based on a percentage entered in the installer setup (ISU 1012). For example if Percent On Time is set to 50%, the ventilation equipment will run at random times during a 1 hour period until it reaches a 50% run time (approximately 30 minutes). Default setting is 30%. Range is 10% to 100% in 10% increments.

Ventilation Fan Control (ISU 1006)

• Tstat Controls Fan The thermostat turns on the ventilator and the fan when ventilation is needed.

• Equip Controls Fan The thermostat turns on the ventilator when ventilation is needed. The fan is controlled by the equipment.

Ventilation Priority (ISU 1012)

• 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 Dehumidifica-

tion 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.

NOTES: ISU 1014 Lockout Ventilation on Humidification or

Dehumidification Calls is not an option when you select ASHRAE is Priority.

The ability to lockout ventilation during the “Sleep” or “Unoccupied” program periods is not an option when you select ASHRAE is Priority.

Ventilation — Outdoor Condition Lockouts (ISU 1013)

Ventilation will not operate when outdoor conditions exceed the lockout settings unless you manually call for ventilation or Ventilation Priority (ISU 1012) is set to ASHRAE is Priority and ventilation is needed to meet ASHRAE. Lockouts can prevent ventilation during extreme weather conditions to keep humid, hot, and cold air out of the home.

NOTE: This feature requires a wired sensor for outdoor

temperature limits, or Internet connection for temperature and humidity lockouts.

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.

Wiring C7089U1006 Outdoor Sensor

CAUTION

Electrical Interference (Noise) Hazard. Can cause erratic system operation.

Keep wiring at least one foot away from large inductive loads such as motors, line starters, lighting ballasts and large power distribution panels. Use shielded cable to reduce interference when rerouting is not possible.

IMPORTANT

Erratic temperature readings from a sensor can occur as a result of any of the wiring practices described below. Avoid these practices to assure correct operation. Use shielded cable to reduce interference if rerouting sensor wiring is not possible.

— Be sure wires have a cable separate from the thermo-

stat cable.

— Do not route temperature sensor wiring with building

power wiring, next to control contactors or near light dimming circuits, electric motors or welding

equipment. — Avoid poor wiring connections. — Avoid intermittent or missing building earth ground.
