Frequently Asked Questions

Temperature offset allows you to change the sensor temperature and temperature displayed on the screen. Offsetting is a way to ensure the temperature in your home matches the temperature reading on your thermostat. If your thermostat is in a cold hallway or a hot living room or someplace the temperature doesn't match the rest of the house, offsetting can help.
Freeze Protection is the setting that turns the heat function on when temperatures fall close to freezing. The factory default is set to 45 F (7.2 C) but can be adjusted to your preference.
If the room temperature falls below the Frost Protect Setpoint, emergency back-up heat will be activated if the equipment has that capability.
Auto Changeover is a feature accessible only for units that can switch between either heating or cooling. When enabled, it will appear in the Thermostat and App as “Auto”. This function allows the system to toggle between heating or cooling automatically, depending on the rise or fall of the ambient temperature.
The Heat/Cool differential works with the Auto Changeover function. The “differential” itself is the temperature difference between the Set Point and the Ambient Temperature required to trigger an auto changeover.

For example, let us assume you are running a unit with auto changeover and the Heat/Cool Differential is set to 4 degrees. If the unit is heating at a setpoint of 75 degrees, an auto changeover to cooling would occur if the ambient temperature reaches 79 degrees. In the same way, if the unit is cooling and has a setpoint of 75 degrees, there will be an auto changeover to heating if the ambient temperature reaches 71 degrees.
The span determines how often the unit cycles on and off. It has a default of 1 degree. If the unit reaches your set point temperature (say 70°F) it will shut off and turn on after it passes the 1 degree span (in this case 68°F)

So, if the thermostat is on heat mode, and the room reaches 70°F, the unit will shut off and won’t turn back on until the room temperature falls to 68°F (Which is past the 1 degree span setting).
This function delays the compressor turn on time after it has been turned off. The factory default is set to 5 minutes, meaning if the unit is turned off and immediately turned on, the compressor will not activate until after 5 minutes. (It is recommended you do not change this setting.)  This function protects potential damage to the compressor when there are frequent on/off cycles.
This determines the maximum Heating set point the user can set on the thermostat.
This determines the minimum Cooling set point the user can set on the thermostat.
Locks or unlocks the physical thermostat buttons, to prevent changes to the settings.
Setback/Eco mode saves energy and money by changing the cooling and/or heating set points to an economical preset temperature when the space in unoccupied.
The Model HTK-01 series can be connected to 6 types of equipment.
  • PTAC (Package Terminal Unit)
  • FCU (Fan Coil Unit / Mini Split)
  • HP (Heat Pump)
  • HHP (Hybrid Heat Pump)
  • UNTY (Unitary AC/Furnace)
The thermostat supports 3 fan operating speeds (HIGH , MEDIUM , and LOW). 
The Habitat model HTK-01 can be paired to control up tp 8 base modules of the same type of units. 
Yes , the HTK-01 series can be configured as programmable or non-programmable thermostat, with Daily, Weekly, and 5+2 scheduling capability. 

To find this parameter in the thermostat, press and hold the "FAN" and "MODE" buttons until you hear one beep and scroll through the options with the FAN button until you see "SCHEDULE" on the screen.
For more information please see the "Programming Manual" booklet.
You may I.D. what firmware the thermostat is operating on by removing the batteries and reinstalling them or by inserting a small paper clip in the hole underneath the base of the thermostat and pressing it in to reset it.
It both cases the thermostat will briefly flash it's firmware number on it's display. 

A "RESTART" maintains all of your settings but reboots the system settings. There are two ways of doing this - One way is to remove and put back your batteries , and the other is,  on the bottom of the thermostat , there is a small paper clip sized hole. By inserting a paper clip sized pin you can reset the concealed button by clicking on it. 
To "RESET" the thermostat which removes all information and restores it back to factory default settings , go into Administrative Settings --> "Factory Reset" --> Press "Y". 
After installing the new base module in the unit, press and hold the small red button on the module until the LED indicator light starts flashing green. Go to the thermostat , Press and Hold the FAN, MODE and DOWN buttons at the same time until the thermostat beeps.
The thermostat and new base module will pair within 60 seconds.
When the paring process is complete the LED on the base module will turn to a steady green and the thermostat's display will show the additional unit number.
For more information see page 11 of "Installation and Pairing Manual" 
The Model HTK-01 thermostat series can be powered by two AA batteries or directly hardwired through a 24volt circuit.   
In non-commercial applications, with alkaline batteries, under normal usage , the battery life should be 12 months. 
The factory default beep sound setting on the thermostat is set to off , to turn on this function, go to Administrative Settings and set the Sound to "Y" (On). 
Please follow these steps when installing a new HTM-01 Base Module:
  • Turn off all power to the unit.

  • Unpair the old Base Module in the thermostat Admin settings:
  • To enter Admin settings, press “FAN” and “MODE” buttons until you hear two beeps.
  • Enter the Admin Code and press “FAN”
  • Scroll to the unpair screen and select “y”.
  • Once selected, wait for the 3 minute countdown to initiate module unpairing.

  • Connect the new Base Module and press the small “Red Button” until the LED light starts flashing “GREEN”.

  • On the thermostat, hold the “Down Arrow”, “Mode” and “FAN” buttons at the same time until you hear a “BEEP”.

  • The thermostat is now in pairing mode and should link with the new Base module in 60 seconds. The Base Module’s LED light will be a solid Green.

  • The thermostat’s screen will show the number “1” paired module. Hit the “FAN” button to scroll through the setup screen to return to the main screen.

  • Go into Admin Settings by pressing “FAN” and “MODE” buttons until you hear two beeps.
  • Enter the Admin Code and press “FAN”
  • Scroll to the unpair screen and select “y”.
  • Once selected, use the arrows to choose the Base Module you want to unpair and press “Fan” to confirm.

If there are multiple Base Modules connected to one thermostat, it can be difficult to find the number assigned to any given base module.

In order to find which number is assigned to a base module, use a pin or a paperclip to press the red button on the module and the LED indicator will flash according to the base module number.

For example, if you want to find Base Module #5, you would go to the base module, press the red button and the LED will flash 5 times.
When there is a water leak in your HVAC unit, the thermostat will shut down the unit and it will send out a beep.  Also the thermostat's display will show an alert on it's screen.
To reset and clear this alarm first ensure that the water sensor is dry and the surrounding area is dry as well.
 On initial touch of the thermostat, the beep will shut off, however to clear the alert and reset your unit, you must press the Up, Down, Fan, and Mode buttons simultaneously. 

Please Note that the alert will not clear and the unit will not be reset if the water sensor continues to sense water. 
Setback/Eco mode may be turned on or off manually with the keypad using the parameter settings, though the mobile application, or with an occupancy sensor.

(Please refer to Page 14 in the Operation Manual)
Temperature Units: To change the temperature units between °F and °C, quickly press and release the Up and Down buttons together.

For more information , please go to page 12 in the OPERATION MANUAL.
