1 Introduction

The BAST-221C is a member of the BASstat BACnet Communicating Thermostat series. It provides multi-stage heating and cooling control in an attractive wall-mounted enclosure with a large LCD display. Intended for use with rooftop units (RTUs), the thermostat can control one or two stages of heating and one or two stages of Direct Expansion (DX) cooling. The BASstat is BACnet compliant and BTL listed to ensure seamless integration into BACnet networks. There are two models with the only difference being the way the thermostat communicates to a BACnet client. One model (B2) is BACnet MS/TP connected and can be routed to BACnet/IP clients using a BASrouter (BASRT-B) be integrated into any 802.11 b/g/n Wi-Fi network. User-side comfort control is accomplished with six buttons – Mode (Heat, Cool, or Ventilation), Fan, Raise (Up Arrow), Lower (Down Arrow), Set, and Power. There also are options to lock select buttons or all buttons on the thermostat. A large and easy to read LCD display indicates setpoint, space temperature and current mode of operation using graphical icons.
The BASstat has a built-in space temperature sensor with provision for remote wired 3kΩ NTC thermistor sensor or temperature value can be sent by another communicating device over the BACnet network. Both models have five relays – two for stage heating, two for stage cooling and one for fan. The BASstat is configurable using its buttons and entering the Engineering Menu or via a network connection to a BACnet client. Contemporary Controls’ free
Discovery Tool can be used for initial discovery and configuration of the thermostat over
BACnet. Control algorithm parameters such as deadband, proportional gain, integral rate, stage trip points and stage widths are all configurable. The BASstat also features configurable short­cycle protection, maximum cycles per hour, fan control and occupancy selection. All states and pending delays are indicated by graphical icons on the thermostat display.
The numerous features available in the BASstat can be configured by the systems integrator to meet user requirements in two different ways. One way is using a button sequence on the thermostat in order to enter the Engineering Menu - which requires physical access to the thermostat. Optionally, the buttons could be locked to limit user access to Engineering Menu after installation is complete. The second method is configuring the thermostat over the BACnet network using a BACnet client device or software such as Contemporary Controls’ free
Discovery Tool (BDT). All features available are configurable using both methods.
. The other model, (BW2) is BACnet/IP over Wi-Fi and can

The BASstat is intended for surface-mount installation at eye-level on a wall, not subjected to direct sunlight or direct air movement. The display (top half) can be removed from its base by loosening the small Philips screw at the bottom of the display. There is no need to remove the screw. Once the display is removed from the base, the base can be mounted onto the wall with appropriate fasteners. The dimensions of the oval mounting holes are 4mm x 6mm allowing for perfect fit adjustments. If a single-gang electrical junction box is to be used, the top and bottom mounting holes will align with the screw holes in the junction box. Thanks to its EEPROM, the BASstat will store its configuration in the event of power loss.

3.1 Terminal Block Pin Assignments

Two 9-pin terminal blocks provide for all field connections. Terminal markings for mechanical equipment follow NEMA DC 3-2003 convention. For single-stage operation, connect Y wire to Y1 and W wire to W1. BACnet MS/TP data communication connections can be found at terminals 16 and 17 and are polarity sensitive. The BASstat (B2 MS/TP model) does not provide End-of-Line termination. If the BASstat-B2 is the first or last device on the MS/TP bus, a termination resistor (120Ω) must be applied across pins 16 and 17 of the input terminal. The remote sensor input (RS) is at terminals 13 and 14. The BASstat is intended to be powered by a Class 2 compliant power source and only accepts 24VAC.

3.2 Limited Power Source

The BASstat thermostats accept 24VAC only with no more than 5VA of power consumption and should be powered by a limited power source complying with the requirements of the National Electric Code (NEC) article 725 or other international codes meeting the same intent of limiting the amount of power of the source. Under NEC article 725, a Class 2 circuit is that portion of the wiring system between the load side of a Class 2 power source and the connected equipment. For AC or DC voltages up to 30 volts, the power rating of a Class 2 power source is limited to 100 VA. The transformer or power supply complying with the Class 2 rating must carry a corresponding listing from a regulatory agency such as Underwriters Laboratories (UL).

3.3 Power Supply Precautions

Internally, the BASstat utilizes a half-wave rectifier and therefore can share the same AC power source with other half-wave rectified devices. Sharing AC power with full-wave rectified devices is NOT recommended. Full-wave rectified devices usually require a dedicated AC power source that has a secondary elevated above ground. Both secondary connections are considered HOT. AC power sources that power several half-wave devices have a common secondary connection called COMMON, LO, or GROUND. This connection might be tied to earth. The other side of the secondary is considered the HOT or HI side of the connection. Connect the HOT side of the secondary to the 24 VAC high side input on the BASstat and the LO side to 24 VAC common on the BASstat. All other half-wave devices sharing the same AC power source need to follow the same convention.
WARNING: Devices powered from a common AC source could be damaged if a mix of half­wave and full-wave rectified devices exist. If you are not sure of the type of rectifier used by another device, do not share the AC source with it.

4 Operation

4.1 User Mode

User-side comfort control is accomplished with six buttons – MODE (Heat, Cool, or Ventilate), FAN (Auto or Continuous), UP, DOWN, SET, and POWER. There are also options to lock select buttons or all buttons on the thermostat to limit user access if required in certain applications. A large LCD display indicates setpoint, space temperature, occupancy status, and current mode of operation using graphical icons.
System modes (Cool, Heat, Ventilate) available to the user are dependent on control type chosen from Engineering Menu (tyPE) or BACnet object [MSV7] Control Type for BW2 model and [MSV8] Control Type for B2 model. (See section 4.2 Control Type of this manual). System modes and button operation may be limited by installation engineer, especially if the thermostat is completely controlled over BACnet network.
The first tier of operation includes the following settings as shown below. To operate the thermostat:
1.
The POWER button toggles between ON or OFF states to start / stop the thermostat. This will disable control (ON/OFF control can be accomplished over BACnet
as well).
2.
At power ON, press any button to start the User Mode operation. Press the MODE
button to toggle between different HVAC operating modes such as Cool, Heat, or Ventilate@Cool and Ventilate@Heat.
Press the UP/ DOWN buttons to increase/decrease temperature
setpoint or rotate the values of a setting. Press the FAN button to toggle fan modes of AUTO or CONTINUOUS. If no AUTO icon is displayed, the fan is in CONTINUOUS fan mode and it will run continuously until commanded off using button on thermostat or BACnet command. If AUTO icon is flashing, the fan is operating under delay timer and will shut off automatically when delay timer expires.
Press the SET button and use UP/ DOWN buttons to toggle the unit between Occupied or Unoccupied states when outside of scheduled operation. Use SET or MODE to apply (SET button can be locked in applications forbidding occupancy state user control).
3.
Thermostat will return to normal display with the last known setting if there’s no button pressed for 10 seconds.

4.2 Control Type

Control Type, System Mode and Algorithm Configuration
Both binary thermostat models (B2 and BW2) support two different control types, selectable in Engineering Menu item (tyPE) or BACnet object [MSV8] Control Type for B2 model or [MSV7] Control Type for BW2 model.
Control type unlike thermostat system mode, is not selectable by the end user, only configurable by the installation engineer using Engineering Mode Menu (manual) or BACnet supervisor using BACnet commands (commanded by BACnet supervisor). The engineer installing the thermostat must decide the control type suitable for the application, set it to a static value, or program the BACnet supervisor to change the control type automatically based on logic for the application requirements such as change of seasons or geolocation. The default control type is set to 2­stage Heating and Cooling with Auto Changeover. This is the most common control type. 2­stage Heating and Cooling with Manual Changeover can be used to limit frequent automatic change of system modes (Cool or Heat).
System modes available to the user are dependent on control type chosen from Engineering Menu (tyPE) or BACnet object [MSV7] Control Type for BW2 model and [MSV8] Control Type for B2 model.
Dual Stage Heat and Cool with Auto Changeover - The default control type in the thermostat is set to Heat and Cool with Auto Changeover. Mostly used for standalone operation. Based on an algorithm using setpoint, current temperature, and deadband, the thermostat will switch between Cool and Heat modes automatically. In this control type, the user will be presented with a choice of Heat or Ventilation@Heat when the thermostat is in Heat mode (automatic), and
Cool or Ventilation@Cool when the thermostat is in Cool mode (automatic).
Dual Stage Heat and Cool with Manual Changeover – This control type is similar to Heat and Cool with Auto Changeover but in this control type the thermostat will wait for a command from
user or BACnet supervisor to switch between Cool and Heat modes. In this control type, the user will be presented with a choice of Heat or Ventilation@Heat when the thermostat is in Heat mode (manual command), and Cool or Ventilation@Cool when the thermostat is in Cool mode (manual command). The user can also choose to switch between Cool and Heat modes using the MODE button.
BACnet controlled – The built-in thermostat algorithm can be bypassed completely, and the thermostat can be controlled over the BACnet network with commands from supervisor device. The logic executing in the supervisor (such as Niagara or Sedona logic) can control the thermostat over the BACnet network. To put the thermostat in BACnet network control mode, use the Lock [AV18] object bit 9: Control DOs by thermostat algorithm “0” (default) or BACnet supervisor “1” (add decimal=512).
Cool Only (nullified/disabled in firmware), and Heat Only (nullified/disabled in firmware) control types are listed in the BACnet object and Engineering Menu object but are not available for use. They are nullified/disabled in the firmware.
Fan Output in Heat Mode
By default, the BASstat thermostat will not provide Fan output signal when in Heat Mode since most HVAC comfort systems such as RTU systems provide their own fan control signal based on a delay after a call for heating. This can be configured from Engineering Menu item (F-Ht) or BACnet object [BV15] Fan Output For Heating. The default value is “0”. To enable fan control signal output for heating coming from the BASstat, set this value to “1”.
Algorithm
• A PID adaptive control algorithm is applied to minimize overshoot, in addition to proportional band (Stage Width) and derivative (Differential) calculation.
• When the thermostat is active (either the heating or cooling stage is on), a “Working
( )” icon will be shown on the LCD.
• Stage 1 operation will show the icon ( ). Stage 2 operation will display ( ).
System Mode
• The default control type is 2-stage cooling and heating with automatic changeover. This makes the thermostat operate fully stand-alone. Control Type can be selected in (tyPe) or [MSV7] or [MSV8]. Manual Changeover control type allows restriction of mode selection to Cool only or Heat only in applications where necessary.
• Occupied Cooling [AV0] and Heating [AV3] set points and Unoccupied Cooling [AV8] and Heating [AV9] setpoints can be set individually for cooling and heating modes, with either manual or automatic changeover control. Minimum deadband [AV7] can be programmed as well.
• For cooling/ heating with manual changeover control, cooling or heating can be selected by pressing the MODE button or using a BACnet command to object [ MSV1]. In application where user control needs to be limited, the lock button function can be used to disable MODE button.
Fan Control Output
• Fan Output for Heating - the fan output for Heat mode is disabled “0” in [BV15] by default. The thermostat lets the RTU circuity control the fan during Heat mode. Fan output can be enabled “1” for Heat mode if desired [BV15].
• Lowest Fan Speed is the speed the fan will default to after a control action (Heating or Cooling). If the lowest fan speed [MSV4] is set as “Stop (1)”, the fan will be automatically shut off after the control action (Heating or Cooling) and a 2-minute fan-off time delay. During this delay time, the AUTO icon will be flashing, and the fan will shut off after the 2-minute time delay expires. If lowest fan speed is set to “Low
(2)” the fan will run continuously after a control action. This feature is useful for thermostat models with multiple fan speeds.
• Fan Mode can be toggled between AUTO or CONTINUOS by using the FAN button
on the thermostat (user) or BACnet object [MSV0] Fan Mode (BACnet supervisor). By default, this value is set to “Auto(1)”, the AUTO icon is displayed and the fan will be controlled automatically. To put the fan in CONTINUOS mode set to “Low(2)” this will cause the fan to run continuously (no AUTO icon is displayed). Fan icon spinning when fan is active. Optionally, the FAN button can be locked to limit user access to this feature or the BACnet supervisor can be programmed to default the thermostat to certain state at the end of an occupancy cycle.

Short Cycle and Maximum Cycles per Hour

• There are short cycle and maximum cycles per hour protection for both cooling and heating modes [AV23 – 26] Cooling Short Cycle Delay, Cooling Maximum Cycles per Hour and Heating Short Cycle Delay, Heating Maximum Cycles per Hour.
• The short cycle time (in minutes) will determine the minimum on time and minimum off time of each stage before changing its state. The default setting is 3 minutes.
• Maximum cycles per hour will count the number of cycles in an hour. When the cycle count reaches the maximum cycles in an hour, it won’t allow additional cycles until the next hour.
• When a stage change is pending due to a Short Cycle Delay or a Maximum Cycle
count, the Clock icon ( ) will appear on the LCD.
• To disable short cycle checking, set the short cycle to 0 minutes. NOTE: Do not use this value unless the heating and cooling equipment is equipped with an internal timer. Damage to equipment may occur.

Occupancy Setting

There are three ways to define thermostat occupancy state.

• Occupancy status (occupied/unoccupied) can be set by a BACnet supervisor using writable object Occupancy Command [BV14]. Use “0” for occupied (occupied setpoints used, sun icon displayed), and “1” for unoccupied (unoccupied setpoints used, moon icon displayed). Occupancy Status [BI0] is a read-only BACnet object indicating current thermostat occupancy state - “0” for occupied, and “1” for unoccupied. The BACnet occupancy command can work in conjunction with SET button (user control) on last-write-wins basis.
• User control of occupancy state is allowed from the SET button. Pressing the SET button and UP/DOWN buttons will toggle the occupancy state. Press MODE or SET buttons to confirm. The SET button can work in conjunction with BACnet occupancy Command [BV14] on last-write-wins basis. The SET button could be locked to limit user control (use Lock [AV18] BACnet object or (LOC) engineering menu item to lock SET button). In this case only the BACnet supervisor can set occupancy states. Occupancy Status [BI0] is a read-only BACnet object indicating current occupancy state.
• When in unoccupied state, a Moon ( ) icon will be displayed on the LCD and the
thermostat will change the set-point temperatures for Cooling and Heating to the Unoccupied Cool Setpoint and Unoccupied Heat Setpoint [AV8 – 9]. When the state changes back to occupied, the thermostat will return to the occupied set-point values for Cooling Temperature Setpoint and Heating Temperature Setpoint [AV0, AV3] and a
sunlight icon( ) will be displayed to indicate occupied state on LCD.

4.3 Engineering Mode Menu

Thermostat configuration can be performed using the engineering mode menu described below or BACnet objects using a BACnet client tool such as Contemporary Controls free
BACnet Discovery Tool (BDT)
trained engineers only, because it is related to system parameters that will affect the control results.
Operation of Engineering Menu
. It is highly suggested that engineering mode be operated by
• At power “ON”, press and hold both the UP and DOWN buttons simultaneously for 5 seconds to enter Engineering Mode menu.
• Press the UP (ascending order of objects in table) or DOWN (descending order of objects in table) buttons to rotate through the menu items. The last item loops back to first item at the end of items in menu. Press the MODE button to enter a submenu item.
• Press the UP or DOWN button to change the setting in the submenu item or hold to speed up setting value change. Press the MODE button to confirm the setting and return to menu item selection. If no button is pressed for 10 seconds, the display will return to the menu item selection. After another 10 seconds, the display will return back to User mode. Settings are not changed unless confirmed using the MODE button.
• To leave Engineering Mode, rotate till (End) menu item appears and press the MODE button. Alternately, pressing no buttons for 10 seconds will return the thermostat back to User mode.

Lock Function Setup and Examples
The 16-bit binary encoded decimal register accessed through Lock [AV17] BACnet object and LOC engineering menu item is used to enable/disable features in the thermostat. The first 10 bits are used (bit 0 ~ bit 9), bits 10~15 are reserved/unused. Bits are represented by their decimal values and are added or subtracted to toggle from “0” to “1”. Add a bit’s decimal value to toggle to “1” or subtract a bit’s decimal value to toggle to “0”. See table below.

4.4 BACnet Objects and Network Configuration

Transmission types (model dependent)
BASstat B2:
• Physical layer: EIA-485
• Protocol: BACnet MS/TP
• Baud rate: 9600-76800bps (38400bps default)
• MAC address: 1 (default)
• Device Instance: 100001
load reset
BASstat BW2:
• Physical layer: Wi-Fi 802.11 b/g/n
• Protocol: BACnet/IP
• UDP Port Number: BAC0 (47808)
• MAC address: Wi-Fi chip MAC address found written on the back side of thermostat or in Engineering Menu item (Phy3). This can assist when multiple Wi-Fi thermostats are installed.
• Device Instance: 100001
Initial Configuration
Initial communication configuration differs depending on whether you are using the BACnet MS/TP model (B2) or BACnet/IP over Wi-Fi model (BW2). All configuration parameters are settable through use of the buttons on thermostat by entering the Engineer Menu, or once installed on the BACnet network, configuration can also be altered using BACnet commands. Network command-based configuration can also be accomplished on the bench using a BACnet
router (B2 MS/TP model) or Wi-Fi enabled laptop/computer/tablet/smart phone (BW2 Wi-Fi
model) and our free BACnet Discovery Tool.
B2 model - MS/TP Communication Configuration
Overview
The BASstat MS/TP thermostat is preconfigured with a MAC address of 1 and default baud rate of 38400bps. To alter this configuration, enter the Engineering Menu by holding down the UP and DOWN buttons simultaneously for 5 seconds. Use the UP and DOWN buttons to navigate through the menu and change menu item values. Use the MODE button to enter a menu item and accept/confirm a selected value. To exit the Engineering Menu, navigate to menu item (End) and press MODE to confirm, or the menu will exit automatically when not used after 5 seconds. BACnet MS/TP model configuration requires setting the baud rate or using the default baud rate of 38.4kbps. A unique MS/TP MAC address is required to distinguish it from other MS/TP devices on the bus (default MAC address = 1). When more than one BASstat is installed at the same time, their MAC addresses must be configured prior to communicating on the BACnet MS/TP bus or communication will fail due to duplicate MAC addresses. A unique Device Instance Number throughout the entire BACnet internetwork is also required to distinguish the device from all other BACnet devices.
End-of-Line Termination
The BASstat does not provide End-of-Line termination. If the BASstat is the first or last device on the MS/TP bus, a termination resistor (120Ω) must be applied across pins 16 and 17 of the input terminal.
Addressing
The MAC address can be set from Engineering Menu item (Addr) with values of 1 - 127. The Baud rate can be set from Engineering Menu item (bAud) 9.6kbps – 76.8kbps. A unique Device Instance Number throughout the entire BACnet internetwork is also required to distinguish the device from all other BACnet devices. Device instance can be modified in Engineering Menu items (dEVH) – high bytes and (dEVL) – low bytes. Device Instance = (dEVH)*1000+(dEVL). Device Instance example: if (dEVH) is set to 4194 and (dEVL) is set to 7, the Device Instance Number = 4194007. Device Instance Number can also be changed by writing to BACnet object [AV21] Device Instance once the thermostat is online. Max masters setting can be set from Engineering Menu item (AdrH), default value is 127.
Reset Settings
Thanks to its EEPROM, the BASstat will store configuration in the event of power loss. All settings can be reset back to default from Engineering Menu item (rSt). Use caution because once this item is selected (MODE button to select), all settings will be reset to their default values.
BW2 model - Wi-Fi Communication Configuration
Overview
The BASstat Wi-Fi thermostat is preconfigured with a BACnet Device Instance of 100001 and a UDP Port Number of 47808 (decimal) equivalent to BAC0 (hexadecimal). To alter this
configuration, enter the Engineering Menu by holding down the UP and DOWN buttons simultaneously for 5 seconds. Use the UP and DOWN buttons to navigate through the menu and change menu item values. Use the MODE button to enter a menu item and accept/confirm a selected value. To exit the Engineering Menu, navigate to menu item (End) and press MODE, or the menu will exit automatically when not used after 5 seconds.
Addressing
A unique Device Instance Number throughout the entire BACnet internetwork is required to distinguish the device from all other BACnet devices. When more than one BASstat is installed at the same time, their Device Instance Number must be configured prior to connecting to the BACnet/IP network or BACnet communication will fail due to duplicate device instances.
Device instance can be modified in Engineering Menu items (dEVH) – high bytes and (dEVL) – low bytes. Device Instance = (dEVH)*1000+(dEVL). Device Instance example: if (dEVH) is set to 4194 and (dEVL) is set to 7, Device Instance Number = 4194007. Device Instance Number can also be changed by writing to BACnet object [AV21] Device Instance once the thermostat is online. The BACnet UDP Port Number can be configured in Engineering Menu item (UdP).
BACnet/IP Wi-Fi (BW2) model will initially boot up as a Wi-Fi Access Point to allow for IP configuration. This requires connecting to the thermostat as an access point for initial configuration using a Wi-Fi enabled laptop/computer/tablet/smart phone. Look for the BASstat­221C-BW2 with its unique SSID of “WiFi-122B-xxxx” and no access point passphrase by default (simply click to connect to Access Point). The digits “xxxx” in “122B-xxxx” are the last 4 digits of the thermostat’s Wi-Fi chip MAC address found written on the back side of the Wi-Fi module. This ensures a unique SSID for discovery and configuration and it can assist in identification of thermostats when multiple Wi-Fi stats are installed on the same site (unique identifier outlined in blue in the image below). This unique identifier can also be viewed in Engineering Menu item (Phy3).
Once connected to the thermostat as an access point, open its web page by typing its default address of 192.168.0.1 with admin for username and no password. Web page pictured below will be presented for IP Network Configuration. The default IP configuration is shown below.
After initial connection using laptop or tablet or smart phone, the Wi-Fi mode in the thermostat can be changed to Infrastructure mode. The local Wi-Fi router/access point can be selected from the Available AP drop-down list, or an AP SSID can be entered manually. Enter the AP
Passphrase to authenticate and connect to the AP.
ATTENTION: When setting up the Wi-Fi router (Access Point) the thermostats will be connected to, make sure you set up a strong access point passphrase (password)! This is required for Wi­Fi client devices to connect to the Wi-Fi router and it is essential to cyber security. Creating a good Wi-Fi password is the first step in creating a secure environment that is inaccessible to unauthorised parties. Use the following tips when creating a Wi-Fi access point passphrase:
• Passphrase should be a minimum of eight characters (maximum 15 characters), the more random the better. Use a mix of letters (uppercase and lowercase), numbers, and symbols.
• Misspelling commonly used words and replacing some of the letters with numbers or symbols is a good practice and makes passwords difficult to guess.
• Avoid using instances like "abc1234", "123456789", "password", "qwerty", "111111", "admin", "iloveyou" and "aaaaaa".
• Do not reuse or repeat passwords across router installations or job sites.
• Change WiFi password regularly (not required but very secure). Provides guidelines for
building maintenance personnel.
• Disable broadcast of SSID. This is a very simple setting which stops the broadcast of the access point SSID, and only authorized parties who know the SSID can connect to it. This is configured in the Wi-Fi router.
• Store passwords in a safe place, limit access to authorized parties only, and provide instructions for password reset and reconfiguring a strong password in cases of reconfiguring the network in the future.
Choose an option for DHCP addressing using the radio buttons.
The thermostat supports DHCP addressing and will acquire an IP address from the router/access point automatically if you chose Enable next to DHCP. If you chose Disable, you must assign an IP Address, Network Mask, and Gateway Address within the Wi-Fi router IP subnet manually.
A reboot of the thermostat is required for new IP configuration to take effect. Click the Save &
Restart button to reboot the thermostat, and you will be prompted to confirm the restart. Click OK to Save New Settings and Restart or click Cancel to revisit IP configuration.
When OK is clicked a confirmation is displayed to indicate configuration is stored in the thermostat’s EEPROM. After reboot, the new thermostat credentials will be admin for user name and the newly configured Access Point’s password for password.
Click OK on the confirmation message and wait 20 seconds for the reboot process to complete.
While rebooting, the thermostat will display “DP” icon in the lower right corner to indicate it is in the process of searching and connecting to the AP. Once the “DP” stops flashing, the thermostat has successfully connected to Wi-Fi access point. After reboot of the thermostat, the new Infrastructure mode with new IP settings will be used. The thermostat will now be connected to the local Wi-Fi network AP selected in configuration screen and will not show up as an access point itself any more. If you are unsure of the thermostat’s IP address, it could be viewed through the Engineering Menu in items (IP-1) for the first octet, (IP-2) for the second octet, (IP-3) for the third, and (IP-4) for the fourth octet of the IP address, or if you have access to the Wi-Fi access point, its “statistics” or “connected devices” web page will show the BASstat BW2’s IP address as well as MAC address (the same address in Engineering Menu items Phy1, Phy2, and Phy3 and the printed MAC on the back of the thermostat Wi-Fi module (outlined in blue above).
Reset Settings
Thanks to its EEPROM, the BASstat will store configuration in the event of power loss. If configuration fails or the thermostat needs to be configured to use a different Wi-Fi access point, the thermostat must be reset and reconfigured. There are 2 reset settings options for the Wi-Fi thermostat:
- Boot will restore Wi-Fi communication parameters to default, but it will maintain control algorithm settings. Select (boot) engineering menu item and press MODE to confirm.
- Reset will restore all values to default and can be selected from engineering menu (rSt).
