5. Setup and Installation

5.1. Battery Installation

  1. Open the battery compartment cover on the back of the thermostat unit.
  2. Insert the two supplied AA alkaline batteries, ensuring correct polarity (+/-).
  3. Close the battery compartment cover. The thermostat display should power on.

5.2. Mounting the Thermostat

The thermostat can be placed on a flat surface using the mounting stand or mounted on a wall using the wall mount bracket.

Desktop Placement:

  1. Attach the mounting stand to the base of the thermostat unit.
  2. Place the thermostat on a stable, flat surface away from direct sunlight, drafts, or heat sources.

Wall Mounting:

5.3. Pairing with the Wireless Relay Box

The Hanicks Pro Series thermostat is designed to pair with existing Honeywell wireless relay boxes (e.g., BDR91). Follow these steps to establish communication:

  1. Ensure your existing Honeywell wireless relay box is powered on.
  2. On the relay box, press and hold the binding button (often labeled 'BIND' or 'RF BIND') for approximately 2-5 seconds until the LED indicator starts flashing. This puts the relay box into pairing mode.
  3. On the Hanicks Pro Series thermostat, navigate to the pairing menu. This is typically accessed by pressing and holding a specific button (e.g., 'MENU' or a dedicated 'BIND' button) for a few seconds. Refer to the on-screen prompts.
  4. Once the thermostat enters pairing mode, it will search for the relay box. The display may show a 'BINDING' or 'PAIRING' message.
  5. Upon successful pairing, the LED on the relay box will stop flashing and remain solid green, and the thermostat display will confirm successful connection (e.g., 'RF OK' or a signal strength indicator).
  6. If pairing fails, ensure the thermostat and relay box are within range and repeat the process.

Note: For detailed visual instructions, consult the installation video provided by Hanicks, often accessible via a QR code in the product packaging or on the product listing page.

6. Operating Instructions

6.1. Setting Date and Time

  1. Press the 'MENU' button.
  2. Navigate to the 'SET TIME/DATE' option using the arrow buttons.
  3. Adjust the year, month, day, hour, and minute using the '+' and '-' buttons. Confirm each setting with 'OK' or 'MENU'.

6.2. Programming the 7-Day Schedule

The thermostat allows for a 7-day programmable schedule with up to 2 on/off cycles per day. Each day can be programmed individually or copied to other days.

  1. Press the 'MENU' button and select 'PROGRAM' or 'SCHEDULE'.
  2. Select the day you wish to program (e.g., 'MON').
  3. Set the desired 'ON' time and temperature for the first heating period.
  4. Set the desired 'OFF' time and temperature (or setback temperature) for the first heating period.
  5. Repeat for the second 'ON' and 'OFF' cycle if required.
  6. Use the 'COPY' function to duplicate settings to other days, or program each day individually.
  7. Save and exit the programming menu.

6.3. Operating Modes

The thermostat typically offers the following operating modes:

  • AUTO (Automatic) Mode: The thermostat follows the programmed 7-day schedule.
  • MAN (Manual) Mode: The thermostat maintains a constant temperature set by the user, overriding the schedule. Adjust the temperature using the '+' and '-' buttons.
  • OFF Mode: The heating system is turned off.

Switch between modes using the dedicated 'MODE' button or by navigating through the 'MENU' options.

6.4. Temperature Adjustment

In AUTO mode, you can temporarily override the current programmed temperature using the '+' or '-' buttons. This temporary override will typically last until the next programmed event or until manually cancelled.

In MAN mode, the '+' and '-' buttons directly adjust the constant target temperature.
