View Auto
This feature allows you to choose between automatic changeover or manual changeover. Changeover refers to the thermostat being switched from heat to cool as the air crosses a certain temperature. Auto changeover switches from heat to cool automatically while manual changeover thermostats must be changed by hand. If you select, changeover will not appear in the “Adjustment Screen ”. Applicable to: Heat/Cool, 2Heat/Cool, 2Cool/Heat and 2Heat/2Cool modes.

Room Offset
This feature allows you to program an offset. In the case that the thermostat is not reading the same temperature as the actual temperature in the room. This setting allows the used to offset the temperature showing on the thermostat.
eg. Actual Room Temperature 72 °F. Direct Sunlight causes Thermostat to show 73 °F. The user can put an offset of -1 °F to get the temperatures to match.

  • Heat: Allows the user to be only in heat mode
  • Cool: Allows the user to be only in cool mode This option is only available when you select “YES” in View Auto options in the Special Functions screen.
  • Applicable to: Heat/Cool, 2Heat/Cool, 2Cool/Heat and 2Heat/2Cool modes.

MODE OPTIONS
This option allows you to select between Room, Floor and Dual sensor modes. If you are setting your Thermostat as a DHW Zone, see Zone Demand on page 9. Selecting DHW will automatically configure your sensor.

  • If you are using an external room thermistor, see page 13 for thermistor switch settings.HBX-THM-0500-Touch-Screen-Programmable-Thermostat-fig-16

Room Mode Option

HBX-THM-0500-Touch-Screen-Programmable-Thermostat-
fig-17

Room Mode
Sensor temperature providing feedback for the specific room or zone being controlled by the thermostat.

Room Mode: Sensor 1

  • None – No external thermistor attached.
  • RM/Ave – averages external 1 and internal sensor, or optional external room sensor (see page 13 for instructions).
  • Outdoor – Uses external sensor to display outdoor temperature.
  • Room – disregards internal sensor, uses external 1.
  • Floor – displays the floor temperature using external 1 sensor.

Dual Mode Option

Dual Mode
Sensor temperature providing feedback for both the air temperature and floor sensor temperatures.

  • Only available when heating modes are the primary function.

Dual Mode: Floor Maximum
The thermostat will not allow the temperature in the floor to go above this value, protecting the integrity of the floor covering. If in a 2 stage heating mode, only the radiant heating contact is turned off.HBX-THM-0500-Touch-
Screen-Programmable-Thermostat-fig-18

Dual Mode: Floor Minimum
The thermostat will not allow the temperature in the floor to go below this value, protecting the integrity of the floor covering.

Dual Mode: Sensor 1
This option will be automatically set to floor sensor.

Floor Mode Option

Floor Mode
Sensor temperature provides feedback from the floor surface to the thermostat. This mode will run the thermostat on floor temperature only.

  • Only available when heating modes are the primary function.

Floor Mode: Differential
When in floor mode, the differential option is set to allow a differential around the target to lessen the chances of short cycling. Ex. A differential of 4°F is 2°F above the setpoint and 2°F below the setpoint.

Floor Mode: Sensor 1
This option will be automatically set to the floor sensor.

SYSTEM SETUP OPTIONS

This selection allows you to access the System Setup menu.

ZONE SETUP OPTIONS

Zone Setup
This setting takes you to the Zone Setup Menu.

Zone Setup: Sequence
This option allows the user to set the zone module sequence order. Select the sequence you would like to set up for the module (1-4, 5-8, 9-12,13-16, 17-20). Adjusting the sequence order can only be done using the first THM-0500 (zone 1) thermostat that is connected to the zone module (ZON-0550). Ex. Sequence order 5-8 are zones 5, 6, 7 and 8.

  • Selecting sequence order (1-4) will set the zone module as the “master”.

Zone Setup: Demand
This option allows the user to determine what happens when the thermostat makes a call.

  • Low – Low-Temperature Demand
  • High – High-Temperature Demand
  • DHW – Domestic Hot Water (Digital Aquastat)
  • Fan – Fancoil Demand
  • Geo – 2-stage heating and 2-stage cooling (only available when geo mode is enabled, see page 5)

Zone Setup: Priority
This option allows the user to set a priority on a zone(s) over another zone (s). Priorities range from 1 (highest) to 7 (lowest). Higher priorities will lock out lower priorities until the demand has been satisfied. Multiple zones can be given the same numbered priority.

The Priority Shield option allows a zone to ignore other priorities from other zones.

  • Priority 1 is a timed priority of 60 minutes, generally used for DHW.

Zone Setup: Password
This option allows the user to see the password to connect to the HBX Zone App. Selecting this option allows you to change the password.

  • No – The password will remain the same
  • Yes – The Thermostat will randomly generate a new password.HBX-THM-0500-Touch-Screen-Programmable-Thermostat-fig-24

Zone Setup: Master ID
With this option, if the thermostat is connected to the first zone module it will display the master ID. If selected it will put the module into “Discovery mode”. If the thermostat is connected to additional zone modules, it will indicate the ID of the master module it is paired to. If selected it will put the module into pairing mode.

Zone Setup: Damper Zone
This option allows you to set the zone as a damper zone. 2 zones and 2 dampers can be set up per zone module. Zones (1 and 3) are zones and (2 and 4) are dampers. No thermostats are needed for dampers. THM-0500 thermostats must be only wired in THM1 and THM3 terminals when using dampers.

  • Default:

Zone Setup: 4 Pipe Zone (Geo Mode Only)

INSTALLATION AND WIRING

MOUNTING INSTRUCTIONS
In order to assure proper room temperature, it is important to identify the ideal location of the thermostat. It should be approximately 5 feet from the floor and at least 1 foot from door openings on an interior wall. Avoid exposing the thermostat to direct sunlight, to air flows (doors, windows, etc.) as well as to heat sources.HBX-THM-0500-Touch-Screen-Programmable-
Thermostat-fig-38

EXTERNAL ROOM THERMISTOR

On the THM-0500, the room thermistor switch is located on the bottom left corner of the thermostat. Toggling this switch will allow the user to alternate between the built in room thermistor on the THM-0500, or an external room thermistor connected to pins 1 and 2 on the THM-0500.
