| 1 | 1 Heat / 1 Cool Heat Pump (No Aux. Heat) | - |
| 2 | Heat Only (2-wire, 3-wire zone valves [Series 20], and normally open zone valves) | - |
| 3 | Heat Only with Fan | - |
| 4 | Cool Only | - |
The installer must select the system type that best matches the HVAC system connected to the thermostat. This ensures that the thermostat correctly controls heating and cooling functions.
Temperature Range Adjustments
The FocusPRO 5000 and 6000 series thermostats allow for customization of temperature range limits. These settings are particularly useful for ensuring that the system operates within safe and efficient parameters:
- Function 27 (Heat Temperature Range Stop): The maximum heat temperature setting can be set to 90°F (32°C). Other available options are within the range of 40–89°F (4.5°C to 32°C).
- Function 28 (Cool Temperature Range Stop): The minimum cool temperature setting can be set to 50°F (10°C). Other options are available within the range of 51–99°F (10.5°C to 37°C).
These settings allow installers to prevent the system from operating outside of acceptable temperature ranges, which can help improve efficiency and prevent system damage.
Fan Control Options
The thermostat allows for the configuration of fan control settings, which can be particularly important in systems that use fan-only operation or require continuous fan cycling for improved air circulation.
Installers can use the UP and DOWN buttons to turn the system on or off during testing. The NEXT button is used to move to the next test or function, while the DONE button terminates the test or saves the current settings.
Installer System Test Mode
The Installer System Test mode is designed to verify that the thermostat can correctly control the HVAC system. This mode allows the installer to test heating, emergency heat, cooling, and fan functions to ensure that the system operates as expected.
