infiNET™ Thermostat: CHV-TSTATRF

Introduction

The CHV-TSTATRF is a wireless networked thermostat featuring infiNET™

wireless technology. The CHV-TSTATRF is designed to be installed easily in place

of a conventional thermostat without requiring additional control wiring. Although it

can be used as a standalone thermostat, the CHV-TSTATRF delivers enhanced

functionality as part of a complete Crestron Home® automation system

communicating via the infiNET wireless control network.

The thermostat is available in three colors: the CHV-TSTATRFA in almond, the

CHV-TSTATRFB in black and the CHV-TSTATRFW in white. For simplicity

within this guide, these thermostats are referred to as CHV-TSTATRF. The features

and specifications for all three thermostats are identical.

Features and Functions

• Wall-mounted heat/cool thermostat

• For baseboard, forced air and heat pump (with auxiliary heat) HVAC

systems

• User selectable Auto mode with single or dual setpoint operation*

infiNET™ Thermostat Crestron CHV-TSTATRF

Heat/Cool Thermostat

The CHV-TSTATRF is designed for heating and cooling control of baseboard,

forced air, heat pump and dual-fuel heat pump HVAC systems. The large backlit

LCD display provides a clear view of current temperature, setpoint, system mode,

fan mode, system status and setup functions. Climate-control features include

separate heat and cool setpoints and adjustable anticipators to prevent overshooting

the desired temperature. Continuous fan operation can be selected when needed for

increased circulation.

infiNET™

Creston’s groundbreaking infiNET wireless technology affords reliable two-way

communications throughout a home or office structure without the need for physical

control wiring. Numerous infiNET thermostats and other devices can be linked to a

control system via a single RF gateway. Employing a 2.4 GHz mesh network

topology, every infiNET device functions as an RF repeater, increasing effective

range and reinforcing the complete network by providing multiple redundant signal

paths within the mesh network. In addition, a dedicated repeater (C2N-MNETRPT,

sold separately) can be added to increase the system range.

NOTE: The CHV-TSTATRF must be powered by 24 Volt AC source and have its

power setting on “24” to allow it to function as a repeater.

Automation System Integration

Its wireless connection to the control system allows the functions of the

CHV-TSTATRF to be controlled from touchpanels, keypads, wireless remotes and

computers to support unlimited flexibility for remote control, scheduling and

integration with other devices and systems. However, in the event that

communication with the control system is disrupted for any reason, the

CHV-TSTATRF will remain operable to control the HVAC system.

Easy Installation

System design, installation and upgrade using infiNET thermostats along with

lighting dimmers and other devices could not be easier. Since there is no control

wiring required, the CHV-TSTATRF can be installed just like any conventional

thermostat.

Setting up a complete network of infiNET devices is simple, utilizing dynamic

discovery (self-install) to locate and acquire each RF device automatically. Setting

the RF ID of each device employs the same convention as Crestron’s familiar TSID

method. The RF ID can also be set manually from the local display. Each device is

programmable using Crestron SIMPL™ Windows

software just like any wired Cresnet® device. Even firmware updates are performed

over the wireless network.

No further action is required to configure the infiNET network. Each device assigned

to a common gateway automatically behaves as a repeater for any other device

within range (approximately 150 feet indoors) and additional repeaters may be added

if necessary. At all times, the infiNET gateway monitors each device on the network,

ignoring any other 2.4 GHz signals and reconfiguring the entire network

automatically in response to new sources of interference and other changes in RF

conditions.

Basic Setup

Basic Thermostat Setup

The following documents the most common CHV-TSTATRF setup requirements. For full details on all setup options, refer to “Advanced Setup” which starts on page

19.

Install two AA batteries (supplied) in the battery compartment.

NOTE: When first setting up the CHV-TSTATRF, batteries are required, even if you plan to power it from a constant 24 VAC supply.

Place the CHV-TSTATRF in the Setup mode by doing the following:

1. Press and hold the FAN button.

2. While the FAN button is being held, press and hold the simultaneously.

3. Hold all three buttons for five seconds, after which the unit will enter Setup mode. The display shows the Temperature Scale function (FC).

Use or to choose the temperature units: F (Fahrenheit), C1 (setpoint in whole degrees Celsius) or C2 (setpoint in half degrees Celsius). Then press MODE twice until the Heat/Cool function is displayed (HC).

and to choose between Heat/Cool (HC), Heat pump (HP) and Dual-fuel

Use Heat Pump (dF) functions. Then press MODE repeatedly until the Power Source function is displayed (Po).

and to choose between 24V always available (24) and steal power (SP).

Use

By default, the CHV-TSTATRF is configured to be powered by two AA alkaline batteries. In addition, in order to extend battery life, the device is able to steal power from the HVAC system by drawing a small amount of current through the heat or cool terminals. It will not draw enough current to cause the external heat or cool relays to close.

More specifically, when the unit is not making a call for heat, it will draw power through the RH and W terminals. When the unit is making a call for heat, it will draw power through the RC and Y terminals. (This will not work if the thermostat has been wired for a cool only application.)

NOTE: The CHV-TSTATRF must be wired for heat control in order to take advantage of the steal power setting.

and buttons

NOTE: The power stealing ability is designed to extend battery life, not to eliminate the need for batteries. Two AA batteries are still required.

NOTE: When the Power Source (Po) function is set to steal power (SP), even when an auxiliary power source is available, the unit will continue to enter a communications sleep state, waking every 30 seconds or one minute (based on the infiNET Sleep Time setting) to exchange data with the control system. Refer to “Remote Operation” on page 27 for details.

Operations & Installation Guide – DOC. 6490A infiNET™ Thermostat: CHV-TSTATRF • 15

infiNET™ Thermostat Crestron CHV-TSTATRF

NOTE: The power stealing function may cause problems with some types of HVAC systems. While rare, the symptom would be a heat or cool call occurring when the thermostat itself does not indicate a heat or cool call. If this occurs, you should change the power setting to “24” and ensure that you have two AA batteries installed. Be aware that this situation will shorten the expected battery life.

If you have wired the thermostat so that 24 Volts AC will always be present on the “C” terminal (refer to “Wiring the CHV-TSTATRF to the HVAC System” which starts on page 10), you can set the unit to run from this power supply, thus eliminating the need for batteries (except during initial setup). The thermostat will run on battery power if 24 VAC is not present. In addition, when the unit detects 24 VAC is present, it will no longer “sleep”, meaning that it will offer real-time communication with the control system.

When shipped from the factory, the CHV-TSTATRF will have a steal power setting. If you plan to power the device from a constant 24 VAC supply, you must still install batteries in order to access Setup mode and change the power setting to “24”.

NOTE: When the unit is powered from a constant 24 VAC supply, there may be a slight discrepancy between the ambient temperature displayed on the thermostat and the actual room temperature. This discrepancy will also be seen when switching from “SP” to “24”. This is normal and the discrepancy will disappear within approximately 10 minutes.

Basic infiNET™ Setup

The MNET ID of the CHV-TSTATRF has been factory set to 01. After an infiNET device is added to an infiNET network, its MNET ID must be changed to a value that can be addressed by the control system program (03 to 20). The MNET IDs of multiple CHV-TSTATRF devices on the same gateway must be unique. MNET IDs are changed locally using the setup parameter ability of the CHV-TSTATRF (refer to “Setup Mode Parameters/Functions” which starts on page 20). They can also be changed from a personal computer (PC) via the Crestron Toolbox™.

When setting the MNET ID, consider the following:

• The MNET ID of each unit must match an ID code specified in the SIMPL Windows or D3 Pro/SystemBuilder program.

• Each network device on the same gateway must have a unique MNET ID.

In Setup mode, press MODE until the infiNET ID (MNET ID) function is displayed (id).

Use or to choose the infiNET ID (must be in the range from 03 to 20). Press MODE to select the infiNET RF Channel (CH).

Each infiNET device communicates with its gateway on one of 16 infiNET channels. The gateway can be set to operate in an auto channel state, in which case it will operate on a single channel but may switch to a new channel if it detects excessive interference. It can also be set to operate in a fixed channel state, in which it will stay on a specified channel indefinitely.

The RF channel on the thermostat must be set to correspond with the gateway with which it will be communicating. For example, if the desired gateway is running in auto channel, the thermostat must be set to auto as well. If the gateway has been set to run on a fixed channel, the thermostat should be set to that specific channel.

16 • infiNET™ Thermostat: CHV-TSTATRF Operations & Installation Guide – DOC. 6490A

Crestron CHV-TSTATRF infiNET™ Thermostat

Use and to choose 11 – 26 for fixed-channel operation, (Au) for auto channel or (0) to disable the radio. Disabling the radio is useful for extending battery life if, for example, you have installed the thermostat prior to installing the gateway and/or control system. Press MODE until the Start infiNET Acquire function is displayed (AC).

Before an infiNET device can be used on an infiNET network, it must first be acquired by a C2N-MNETGW gateway that is connected to a Cresnet network.

NOTE: An infiNET device can be acquired by only one gateway.

To acquire the CHV-TSTATRF, perform the following procedure:

1. Ensure the unit is in Setup mode (refer to “Basic Thermostat Setup” on page 15 or “Setup Mode” which starts on page 19) and that Acquire mode (AC) is selected.

2. Put the C2N-MNETGW in the Acquire mode, from the unit itself by pressing ACQUIRE or from Toolbox, as described in the latest revision of the C2N-MNETGW guide (Doc. 6317), which is available for download from the Crestron website (http://www.crestron.com/manuals ACQUIRE LED lights.

). The gateway

NOTE: In environments where multiple gateways are installed, only one gateway should be in Acquire mode at a time.

3. Press and simultaneously on the CHV-TSTATRF to start the acquire process: display shows flashing “—” (in progress). When finished, display shows “00” (finished, found gateway) or “E#” (finished, could not find gateway), where # represents an error code.

NOTE: The acquire process can take up to five minutes, depending on the RF channel. Please allow enough time for process to complete.

NOTE: “E0” indicates that search time has expired and no gateway was found. “E1” indicates the RF channel is set to “0” (disabled). To enable the RF channel, refer to “infiNET RF Channel” in “Setup Mode Parameters/Functions” which starts on page 20.

NOTE: To cancel an acquire process before it has completed, press the buttons simultaneously.

After the process is complete, take the C2N-MNETGW out of the Acquire mode by pressing ACQUIRE on the gateway. Refer to the latest revision of the C2N-MNETGW guide (Doc. 6317).

To exit from Setup mode, press the FAN button on the CHV-TSTATRF.

and

The Fan icon will indicate the status of infiNET communication:

• Solid (non-blinking): Communication with control processor established via gateway.

• Two brief blinks every eight seconds: Communication with gateway established but control system is not addressing this MNET ID. It is possible the MNET ID of the device (or the gateway ID) is not set to match the MNET ID of the D3 Pro, SystemBuilder or SIMPL Windows program.

NOTES

Lower setting results in more frequent cycles and faster response (tighter regulation). Higher setting results in less frequent cycles and slower response (looser regulation). The default value should suffice in nearly all installations.

Heat pump systems have performance restrictions based on outdoor temperature. This setting is the minimum outdoor temperature at which the heat pump (or dual-fuel heat pump) system will run.

Aux heat operation is locked out when outdoor temperature exceeds the Aux Heat Balance Point. Dual-fuel systems do not allow both the heat pump and the aux to run at the same time.

Heat pump systems can allow both the heat pump and aux to run at the same time. This sets the ambient temperature threshold to trigger aux heat in addition to the heat pump.

Most heat systems handle the fan call if required. If the system requires the thermostat to control the fan during heat calls, set this parameter to “Y”.

Indicates the mode in which the thermostat is operating. Will automatically be engaged for heat pump or dual-fuel heat pump systems. If not required, it should be disabled to extend battery life.

infiNET™ Thermostat Crestron CHV-TSTATRF

Operation

System Mode

The MODE button on the CHV-TSTATRF will cycle the unit through all available system modes in the following order: Off, Heat, Emergency Heat (for heat pump and dual-fuel systems), Cool and Auto (if enabled in Setup).

The system mode will change upon release of the MODE button and the selected mode will become operational three seconds after the mode has been entered.

Off Mode

In Off mode, all HVAC systems are disabled.

Heat Mode

In Heat mode, the thermostat uses the heating system to maintain the setpoint temperature.

Emergency Heat Mode

In Emergency Heat mode, the thermostat uses only the auxiliary heat output on heat pump or dual-fuel systems to maintain the setpoint temperature.

NOTE: Emergency Heat mode can only be accessed when heat/cool type has been set to “Heat pump” or “Dual-Fuel Heat pump”. This setting can be useful when the heat pump is being serviced or when there is an unexpected problem with it. The display will flash the “flame” icon when the system is in Emergency Heat mode.

Cool Mode

In Cool mode, the thermostat uses the cooling system to maintain the setpoint temperature.

Auto Mode

NOTE: Auto mode support requires firmware version 1.005.0005 or later.

In Auto mode, the thermostat allows the system to switch between Heat and Cool automatically as needed to maintain the setpoint temperature. By default, the CHV-TSTATRF has been configured with Auto mode disabled, meaning it is not available from the thermostat itself or via another interface such as a touchpanel.

In order to enable Auto mode, you must enter Setup mode and change the “AU” setting from “--” to either “d” (dual setpoint) or “S” (single setpoint). Refer to “Setup Mode” which starts on page 19 for details.

Once Auto mode has been enabled, you can access it from the CHV-TSTATRF controls as follows:

1. Press the MODE button until both the flame appear in the display. This indicates Auto mode is now active.

or buttons (or

Dual Setpoint Auto Mode (“AU” = “d” in Setup Mode)

In dual setpoint Auto mode, separate heat and cool setpoints are used. When the ambient temperature drops below the heat setpoint, the unit will call for heat to maintain the heat setpoint. When the ambient temperature rises above the heat setpoint, the unit will not call for cooling until the temperature exceeds the cool setpoint. When the ambient temperature drops below the cool setpoint, the unit will not call for heating until the temperature is below the heat setpoint.

When dual setpoint Auto mode has been enabled, the Auto Dead Band is used to maintain a minimum separation between the heat and cool setpoints. If this separation is violated by a setpoint adjustment, the other setpoint will be automatically adjusted.

For example, if the heat setpoint is at 68 degrees, the cool setpoint is at 72 degrees and the Auto Dead Band is set to 4 degrees, if you lower the cool setpoint to 71 degrees, the heat setpoint will automatically be adjusted to 67 degrees to maintain the 4 degree Auto Dead Band separation.

In dual setpoint Auto mode, the CHV-TSTATRF display will indicate whichever setpoint is closer to the ambient temperature. Both the heat and cool setpoints can be viewed simultaneously using a touchpanel.

Single Setpoint Auto Mode (“AU” = “S” in Setup Mode)

In single setpoint Auto mode, a single setpoint is used for regulation at all times, regardless of whether the system is heating or cooling. The Auto Dead Band (“db”) setup parameter is used to determine when to switch between heating and cooling.

For example, if the setpoint is at 70 degrees and the Auto Dead Band is set to 2 degrees, if the system is cooling, it will not start heating until the ambient temperature drops below 68 degrees (setpoint – Auto Dead Band). Once the unit has switched to heating, it will not resume cooling until the ambient temperature rises above 72 degrees (setpoint + Auto Dead Band).

A larger value for the Auto Dead Band setting will result in less cycling between heating and cooling but can result in large temperature swings during the course of the day. Smaller values for the Auto Dead Band setting will result in tighter temperature regulation but more frequent cycling between heating and cooling.

NOTE: When using a single setpoint, the CHV-TSTATRF has a 20-minute change limiter to prevent system toggling.

Operations & Installation Guide – DOC. 6490A infiNET™ Thermostat: CHV-TSTATRF • 25

infiNET™ Thermostat Crestron CHV-TSTATRF

Fan

The FAN button toggles the fan setting between fan AUTO and fan ON. When set to AUTO, a fan call will be made whenever the system makes a cool call or when the system makes a heat call or auxiliary heat call (if the HF setup parameter is set to “Y”). When set to ON the fan will always run.

Setpoints

The setpoint is the user selectable temperature you want the system to maintain.

and buttons will change the current setpoint by one degree F or C (if

The Temperature Scale is set to “F” or “C1”) or by one half degree C (if Temperature Scale is set to “C2”).

NOTE: While the setpoint is being adjusted, if it is set to a half-degree increment, the integer portion of the number will be displayed and will alternate with “_5” every quarter second for a period of four seconds after the last adjustment. After four seconds, only the integer portion of the number will be displayed.

If the or buttons is held down for two seconds, the unit will enter an autorepeat state and the setpoint will adjust rapidly until the button is released or until the upper (or lower) limit is reached.

Some users will want to have setpoints change automatically based on the day of the week and the time of day. For example, in the winter they may want to lower the heat setpoint while they sleep to lower heating costs. To accommodate this, the CHV-TSTATRF provides a “Scheduled Heat Setpoint” and a “Scheduled Cool Setpoint” which can be specified by the control system program. This is handled automatically by the “Crestron CHV-TSTATRF w/5-2 Scheduler” module provided with the Crestron Database. Refer to “Programming with SIMPL Windows” which starts on page 30 for more details about how to add this module to your program.

For dual setpoint operation, refer to “Auto Mode” which starts on page 24.

Hold

Hold allows the user to adjust the setpoint and will maintain that setpoint until the unit is taken out of Hold. This means that any change to the scheduled heat or cool setpoint that occurs while in Hold will be ignored until the unit is taken out of Hold.

Pressing the MODE and FAN buttons simultaneously will cause the unit to enter Hold if Hold is not yet active and the system mode is Heat, Emergency Heat or Cool.

Pressing the MODE and FAN buttons simultaneously when Hold is active will cause the unit to exit from Hold and recall either the scheduled heat setpoint or scheduled cool setpoint as appropriate to the system mode.

If the system is in single setpoint Auto mode, exiting from Hold will recall the scheduled auto setpoint. If the system is in dual setpoint Auto mode, upon exiting from Hold, the auto cool setpoint becomes the scheduled cool setpoint and the auto heat setpoint becomes the scheduled heat setpoint.

Pressing the MODE and FAN buttons simultaneously when the system mode is Off will have no effect.

When Hold is active, the unit will continue to adjust the current setpoint when the

buttons are pressed. The unit will also continue to adjust the current setpoint

or when the setpoint signal from the control system changes.

Crestron CHV-TSTATRF infiNET™ Thermostat

When the system mode changes to Heat or Emergency Heat, the current setpoint will be set to the scheduled heat setpoint.

When the system mode changes to Cool, the current setpoint will be set to the scheduled cool setpoint.

Remote Operation

As an infiNET device, the CHV-TSTATRF can be controlled remotely via a Crestron control system. Most often, control of the thermostat will be achieved via a touchpanel or web-based graphical interface. In order to extend battery life, the thermostat will only communicate with the control system once every 30 seconds or one minute, based on the infiNET Sleep Time setting. Because of this, there will be a noticeable delay between the time a button is pressed on a touchpanel and when the thermostat reacts to the command. To account for this, the CHV-TSTATRF modules written by Crestron and provided in the Crestron Database will mimic the feedback from the thermostat so that the user will see an immediate response on the touchpanel.

Likewise, pressing a local button on the thermostat (for example, setpoint raise or lower) will not cause an immediate change to the corresponding display on a touchpanel. Instead, the thermostat will wake up approximately 10 seconds after the last button press to send its updated status to the control system.

NOTE: When the CHV-TSTATRF is powered via a constant 24 VAC supply, it will not go to sleep.

Troubleshooting

The following table provides corrective action for possible trouble situations. If further assistance is required, please contact a Crestron customer service representative.

CHV-TSTATRF Troubleshooting

TROUBLE POSSIBLE

CAUSE(S)

No display

Device does not follow control system commands.

Heating/Cooling system is not operating.

No power from system.

Incorrect mounting to back plate.

Device is not communicating with the C2N-MNETGW.

MNET ID of device (or the gateway ID) is not set to match the MNET ID of the SIMPL Windows program.

Device has entered a state of “hibernation”.

No power to thermostat.

CORRECTIVE ACTION

Check for +24V on C connector. Check circuit breaker powering furnace or boiler. Check thermostat wiring. Check batteries (if running on battery power).

Check thermostat mounting.

Open Crestron Toolbox and select the Network Device Tree. Expand the tree until the gateway to be managed is selected. Right-click the NET ID of the selected gateway to open the sub-menu and select Functions | MNET Gateway… If device is not listed, acquire the device to the infiNET network (refer to ”Basic Thermostat Setup” which starts on page 15).

Use the Network Device Tree infiNET network in Crestron Toolbox to poll the infiNET network. Verify that the MNET ID for the infiNET device is set to match the MNET ID specified in the SIMPL Windows program.

If the thermostat is unable to locate its gateway for a period of one hour, in order to prevent excess battery usage, it will hibernate. In this state, it will only look for the gateway once every 20 minutes. To remedy this, press any button on the thermostat. It should look for the gateway within 10 seconds.

Check circuit breaker. Check for +24V on C connector. Check circuit breaker powering furnace or boiler. Recheck wiring connections. Check batteries, replace if necessary.

Crestron CHV-TSTATRF infiNET™ Thermostat

If the CHV-TSTATRF goes into bootloader, the large seven-segment display will show “Ld”, except when in Setup mode. All other LCD segments will be off. All button presses will be ignored, except for the sequence which enters Setup mode (refer to “Setup Mode” which starts on page 19).

From the bootloader, Setup mode will support only the following functions:

• Check Firmware Version (rE)

• infiNET ID (id)

• infiNET RF Channel (CH)

• Start infiNET Acquire (AC)

• Unacquire Gateway (UA)

To restore functionality, try cycling power to the CHV-TSTATRF. If unit remains in bootloader, you should resend the latest firmware using Crestron Toolbox.

NOTE: To manually enter bootloader, press and hold the MODE button for 10 seconds during unit power up.

Appendix: About Heat Pumps

A heat pump extracts available heat from one area and transfers it to another. Even cold air contains some heat and heat pumps can extract heat from the outside air on a cold day and transfer it indoors to maintain a comfortable temperature. A heat pump also works in reverse during the summer, extracting heat from indoors and transferring it outdoors.

In the heating mode, the efficiency of a heat pump decreases as the outdoor air temperature decreases.

Heat Pump Operation

Heat flows naturally from a warm area to a cooler area and the heat pump takes advantage of this principle. The heat pump essentially consists of a compressor, an inside coil and fan and an outside coil and fan. A refrigerant flows inside the coils, under pressure applied by the compressor.

The refrigerant boils at a very low temperature (as low as -15° F) and becomes a vapor, just as water becomes a vapor (steam) when boiled. This vapor is sucked into the compressor where it becomes a high pressure, high temperature vapor.

When heating, the refrigerant is then forced through a coil within part of the heat pump located indoors. A fan blows cool air over the coil, the vapor cools, turns back to a liquid, releasing heat that is blown through a duct system to heat the house.

The cycle begins again as the cooled liquid refrigerant is pumped back outside after releasing it’s heat. On the way, it passes through an expansion valve, lowering the refrigerant's pressure and temperature again so it can boil more easily in the outdoor coil.

In its cooling mode the heat pump system works in reverse, extracting available heat from indoors and transferring it outside.

Heat pumps are most economical when they can be used year-round for both winter heating and summer cooling.

The efficiency of a heat pump varies significantly with the outdoor temperature. While a heat pump may be twice as efficient as a conventional heating system at 50°F. When the outdoor temperature drops to less than 30°F, the heat pump must be supplemented with an auxiliary heating system such as electric resistance. At temperatures of 15°F or less the heat pump may shut off and the backup heating system takes over. This is the heat pump balance point.

In a dual-fuel system, the heat pump is supplemented with a standard furnace, which takes over when it becomes more efficient than the heat pump at very low temperatures. The heat pump type setting (HP) of the Heat/Cool Type (HC) setup parameter will allow aux heat to stage with the heat pump. A dual-fuel type setting (dF) will not allow both systems to run at the same time.

Glossary

Anticipators

Used to anticipate the drop or rise in temperature and energize the appropriate system before reaching the set point. Anticipators affect how tightly the setpoint temperature is maintained.

Auto Dead Band

Sets the minimum separation in auto mode between heat and cool setpoints (with dual setpoints) or maximum drift before system latches alternate mode (with single setpoint).

Balance Point

At low outdoor temperatures, the refrigeration cycle of a heat pump will not be able to supply the heating requirements without the aid of a supplementary heat source. At higher outdoor temperatures, it is inefficient to use supplementary heat.

The heat pump balance point sets the minimum outdoor temperature required to allow operation of the heat pump. Additionally, for conventional heat pump system types (Heat/Cool Type setup parameter = HP), the AuxHeat Balance Point sets the maximum outdoor temperature to allow operation of the auxiliary heat.

Since dual fuel system types only allow operation of one system at a time, only one balance point is available.

Blower (Fan)

An air-handling device for moving air in a distribution system.

Call

A call is the action taken by the thermostat when it sends a signal to turn on the heating or cooling system.

Dual Fuel

A heat pump used in conjunction with an existing fossil fueled furnace.

Emergency Heat (Supplementary Electric Heat)

The auxiliary (AUX) or emergency heat provided at temperatures below a heat pump's balance point. It is usually electrical resistance heat.

Extended Cool

Extends the cool setpoint range to the full auto range of 38 to 99°F.

Forced Air

A type of heating system that uses a blower motor to move air through the furnace and into the ductwork.

Furnace

Equipment used to convert heating energy, such as fuel, oil, gas or electricity, to usable heat. It usually contains a heat exchanger, a blower and the controls to operate the system.

Heat Pump

A unit that both cools and heats. A heat pump system can be either a split system or a packaged system. A heat pump can be used in conjunction with a gas/oil/LP furnace (using the furnace instead of electric resistance heat when temperatures fall below about 35º F).

Humidity

The total amount of moisture in air. Relative humidity (RH) is the amount of moisture in air, relative to its total capability based upon its temperature (dew point). Moisture will condense on surfaces that are below this dew point.

HVAC

Heating, ventilation and air conditioning.

Interstage Differential

The proportional temperature error (0.5 to 3.0º) to trigger the second stage (2-stage only), such as the aux heat for a heat pump type system.

Run Fan in Heat Calls

A device setting that activates the fan output during heat (W) calls. (For heat pump or dual fuel system types, this setting activates the fan during calls for auxiliary heat.

Setpoint

The user selectable temperature you want the system to maintain.

Time Delay (Timer Guards)

Refers to a safety device or circuit that will not allow restart for three minutes.
