This option is only available in Geo Mode. You must set Geo mode to enable this function. This option allows you to dim the idle mode screen to a darker setting.
• Page 7: View Auto 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. Room Offset allows you to program an offset if the thermostat is not reading the same temperature as the actual temperature in the room. You can put an offset of -1 °F to match the temperatures. Setbacks allows you to program a setback to maximize energy during time frames where the zone may be vacant. You can program up to 4 setbacks when selecting time periods in the schedules menu. Geo Mode allows you to control 2 or 4 pipe systems for geothermal applications. This mode can only be turned on/off using the first THM-0500 thermostat connected to the ZON-0550 Controller. Default is a 2 pipe system; to change to a 4 pipe system, go to zone setup options.
• Page 8: Setup Menu allows you to view the main options. Pressing the back icon returns you to the home screen or setup menu. To select an option, touch any item to adjust its setting. Schedule options can be accessed by touching schedule on the display. Weekday programs allow adjustment of four time periods. The back option returns to the previous screen. There must be a minimum of 2°F differential between hot and cold settings. Cooling must be a minimum of 2°F higher than heating. Weekend programs also allow adjustment of four time periods. A cooling setpoint is available when the thermostat has any cooling function.
• Page 9: Schedules Set the temperature for when the zone is in Away Mode. Away Mode can only be set on the thermostat if setbacks are enabled in the System Function screen options. Away mode will override the schedule to a lower/higher temperature. When Setbacks are set, use this to change the minimum/maximum temperature for your zone depending on if your zone is set up for heating or cooling. If the temperature in the zone falls below/rises above this temperature, heating or cooling will come on. Change the minimum temperature for your zone. If the temperature in the zone falls below this temperature, heating will come on. Change the maximum temperature for your zone. If the temperature in the zone increases above this temperature, cooling will come on. This setting only applies to heating/cooling modes.
• Page 10: Changeover Setup menu Auto: this option allows you to change automatically from heat mode to cool mode or vice versa Heat: allows the user to be only in heat mode Cool: allows the user to be only in cool mode System setup Time: 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 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 If you are using an external room thermistor, see page 13 for thermistor switch settings
• Page 11: Dual mode option allows for temperature feedback from both air and floor sensors. The thermostat will not allow the floor temperature to exceed the maximum value to protect the floor covering. The thermostat will not allow the floor temperature to drop below the minimum value to protect the floor covering. In a two-stage heating mode, only the radiant heating contact is turned off. The floor maximum and minimum settings are adjustable. Sensor 1 is automatically set to the floor sensor. Mode setup is essential for configuring dual mode settings. The maximum floor temperature is set to 80°F. The minimum floor temperature is set to 70°F. The dual mode setup is crucial for maintaining optimal floor temperature.
• Page 12: Floor mode allows the thermostat to operate based on floor temperature only. The differential option in floor mode helps reduce short cycling by setting a range around the target temperature. A differential of 4°F means the temperature can vary 2°F above and below the setpoint. The floor mode sensor is automatically set to the floor sensor. Access to the system setup menu is available through the setup options. Changeover mode can be set to automatic. The setup menu includes scheduling options. Floor mode is only available when heating modes are the primary function. Sensor temperature provides feedback from the floor surface to the thermostat. The maximum floor temperature can be set for sensor 1.
• Page 13: Zone Setup options This setting takes you to the Zone Setup Menu. This option allows the user to set the zone module sequence order. Adjusting the sequence order can only be done using the first THM-0500 thermostat connected to the zone module. Selecting sequence order (1-4) will set the zone module as the “master”. This option allows the user to determine what happens when the thermostat makes a call. Demand options include low temperature demand, high temperature demand, domestic hot water, and fancoil demand. This option allows the user to set a priority on a zone(s) over other zone(s). Priorities range from 1 (highest) to 7 (lowest). Higher priorities will lock out lower priorities until the demand has been satisfied. The Priority Shield option allows a zone to ignore other priorities from other zones.
• Page 14: Zone Setup 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. 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. This option allows you to set the zone as a damper zone. 2 zones and 2 dampers can be set up per zone module. THM-0500 thermostats must be only wired in THM1 and THM3 terminals when using dampers. This option allows you to control a 4 pipe system in a geothermal application. This setting takes you to the Fancoil Setup Menu.
• Page 15: Fancoil setup includes several options for fan operation. The fan on demand option activates the fan with any fancoil demand. Zone on demand turns the zone pump on with any fancoil demand. Temperature averaging averages the temperature between thermostats to control heating or cooling. Fan mode settings include off, on, and intermittent operation. The intermittent fan setting allows for specific on/off times for the fan. The fan can be set to operate for a defined duration, applicable only when in intermittent mode. Fan operation can be customized based on user preferences for heating and cooling. Each setting impacts how the fancoil responds to temperature changes. Proper configuration of these settings ensures efficient climate control.
• Page 16: Fancoil Setup Fan on demand Fancoil Mode INT: Intermittent Fan Off Sets the amount of time that must pass before the fan can come on again. System Setup This option will change the thermostat temperature to either Celsius or Fahrenheit. Stage Delay Use this setting to adjust the lag time between stage 1 and stage 2 coming on. This option is only available in 2 stage applications. Sync Code This number is the identifier used in the HBX Zoning App to connect to your thermostat.
