Heating Differentials
The first stage heat turns on when the air temperature falls 1.5°F (1°C) below the
Heat To setting and shuts off when the air temperature reaches the Heat To setting.
The second, third and fourth stage heat each have an adjustable differential and time
delay setting to determine when the stage turns on, and shut off when they reach 1.5,
1.0, and 0.5°F (0.75, 0.5, and 0.25°C) of the Heat To setting respectively.
Radiant Floor Heating
Radiant floor heating is operated differently than other heating types due to the large
time delays to heat and cool the slab. When Radiant Floor Heating is selected in the
setup menu, the W1 relay operates using Pulse Width Modulation. This improves
comfort for radiant systems with high mass floors.
• 100% on time at Heat To setting -1.5 ° F
• 50% on time at Heat To setting
• 0% on time at Heat To setting + 1.5 ° F
Room Sensor and Averaging
The room temperature can be measured using a combination of the built-in and
auxiliary sensors.
• Built-in room sensor only
• Built-in room sensor with auxiliary rooom sensor(s) (temperature is averaged)
• Auxiliary room sensor only
Floor Sensor for Radiant Floor Heating
If a floor sensor is connected, floor minimum and maximum settings are available.
For a combination of air and floor temperature control, leave the internal air sensor on
in the setup menu. A floor minimum can be used to prevent a fast drop in temperature
caused by receding solar exposure. This operation is recommended for areas heated

12 of 36
by afternoon sun through large windows. When the sun sets, it can take a long time
for the floors to get warm again. This may cause the room to cool off too much in the
early evening. A floor minimum setting can help with this condition by maintaining a
floor minimum temperature. Keep in mind the floor minimum temperature will override
the air temperature, and if set too high, may overheat the room.
A floor maximum is recommended for rooms with hardwood floors. Setting floor minimum
and maximum temperatures is a way of enhancing the comfort of the living space while
protecting floor coverings.
If there are more than one floor temperature sensors, the temperature is averaged.
Cooling Differentials
The first stage cooling turns on when the air temperature rises 1.5°F (1°C) above the
Cool To setting and shuts off when the air temperature reaches the Cool To setting.
The second stage cooling has an adjustable differential and time delay setting to
determine when the stage turns on, and shuts off when it reaches 0.5°F (0.25°C)
above the Cool To setting.
Heat Pump Balance Point
An air source heat pump's Coefficient of Performance (COP) declines with falling
outdoor air temperature. The Balance Point is the outdoor temperature at which it is
more economical to shut off the heat pump (relays Y1 and Y2) and operate the backup
heating equipment (relays W1 and W2).
Dual Fuel
Dual fuel systems include a heat pump together with a backup heat source such as
a furnace or a hydronic fan coil. When Dual Fuel is set to on, the heat pump (relays
Y1 and Y2) is shut off whenever the backup heating equipment (relays W1 and W2)
is operating.
Warm Weather Shut Down (WWSD)
The heating system can automatically shut off based upon the outdoor temperature
and the WWSD setting. This provides a convenient way to shut off the heating system.
Cold Weather Shut Down (CWSD)
The cooling system can automatically shut off based upon the outdoor temperature
and CWSD setting. This prevents unwanted cooling during the winter.
Relative Humidity Sensor
The thermostat includes an internal relative humidity (RH) sensor and has the option
to connect to an external RH sensor. The installer has the option to disable the internal
RH sensor when an external RH sensor is installed. When both the internal and external
RH sensors are enabled, the RH reading is averaged.
Humidifier Operation
The thermostat controls the relative humidity (RH) by operating either the Accessory
1 or Accessory 2 relays. This is an installer configurable setting. When the RH is
below the Humidify To setting by 3%, the Accessory 1 or 2 relay is closed to operate
a humidifier. The humidifier is shut off when the RH reaches the Humidify To setting.
Relative Humidity Operation ------------------------------------------------------------------------------------

13 of 36
The thermostat can operate 3 types of humidifiers:
Stand Alone • The humidifier is not connected to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
Steam • The steam humidifier is ducted to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
• Requires the system fan to turn on when operating.
Evaporative • A drum style humidifier which requires the heating system to
operate to evaporate the water.
• This system requires the system fan to operate.
• The thermostat Mode must be set to Heat or Auto.
Humidifier Window Protection
During cold weather, condensation will form on windows when the relative humidity
(RH) is too high. The optional window protection feature automatically calculates the
indoor dew point based upon the outdoor temperature and the quality of the windows
installed. The humidifier is then operated to the highest possible RH that is below the
Humidify To setting.
Dehumidifier Operation
The thermostat controls the relative humidity (RH) by operating either the Accessory
1 or Accessory 2 relay. This is an installer configurable setting. When the RH is above
the Dehumidify To setting by 3%, the Accessory 1 or 2 relay is closed to operate the
dehumidifier. The dehumidifier is shut off when the RH reaches the Dehumidify To setting.
The thermostat can operate 2 types of dehumidifiers:
Stand Alone • The dehumidifier is not connected to the HVAC system.
• The thermostat Mode can be set to Heat, Cool, Auto or Off.
DX Coil • The HVAC cooling system is used for dehumidification.
• The Accessory 1 or Accessory 2 relay activates the DHUM
operation on the air handling unit to operate the system fan at low
speed.
• The cooling compressor Y1 and Y2 relays are operated. The
chilled DX coil condenses moisture from the air.
• The cooling system can over cool the room temperature by 2°F
(1°C) during dehumidification.
Ventilation with fresh outdoor air is important for maintaining indoor air quality. The
thermostat can operate a heat recovery ventilator (HRV) or energy recovery ventilator
(ERV) on a timer by closing the Accessory 1 relay to operate the ventilator fan at low
speed.
The thermostat supports water-to-air heat pump systems that absorb or reject heat to a
hydronic building loop. Whenever the heat pump compressor Y1 or Y2 relay is turned
on, the Accessory 1 relay closes to open a hydronic zone valve. This allows variable
speed pumps on the hydronic loop to operate at lower speeds when the heat pump is
off, thereby saving electrical energy.

WiFi and Connectivity Troubleshooting ------------------------------- -------------------------------
WiFi Connection Status
Press  > WiFi > WiFi:On >  to view the
thermostat connection status.
(1) WiFi Signal Strength
• The WiFi signal must measure between 0
and -69 dB to have a reliable connection
to the Watts cloud.
• A WiFi extender is recommended to be
installed if the WiFi signal is between -70
to -100 dB.
(2) Internet Connected
• The WiFi information screen will show
Internet Connected when the thermostat
is connected to the router and there is a
connection to the Internet.
(3) IoT Connected
• The thermostat connection status will
show IoT Connected when connected
to the Watts Cloud and the thermostat is
ready to be registered to the app.
If IoT is not connected, please follow these
steps:
Check Password
• Double check that you are using the correct
WiFi network and password.
• The password is limited to 32 characters,
and can include upper and lower case
letters, numbers, special characters and
spaces. A space counts as a character.
• The thermostat supports WPA2-Personal
password security.
Power Off and On
• Power the thermostat off. Next, power the
router off, wait 10 seconds, then power
on and wait for the Internet status to be
on. Then power the thermostat on.
Check Router & Firewall
Consult the router manual or Internet Service
Provider (ISP) for assistance with router
setup with these configurations:
• The router must provide a 2.4 GHz signal.
The thermostat is not compatible with 5
GHz networks.
• The router is using WPA2-Personal
security.
• The router has DHCP enabled with enough
available addresses for all Internet devices.
• The router firewall is not blocking the
outbound UDP or TCP ports: 53, 123,
443, 8883.
• The router firewall is not blocking
connections to *.azure-devices.net
• The router firewall is not blocking the
thermostat based upon a MAC filter list.
Network Troubleshooting
• tekmar provides free access to a network
troubleshooting tool called RouteThis
Helps.
• Download the app from the App Store or
Google Play Store to your mobile device.
• Enter code "TEKM" and click "Network
scan". The app will provide further
instructions.
Create a WiFi Hotspot
• If you are unable to connect to the WiFi
network, try creating a WiFi Hotspot on
your mobile device to bypass the router.
