3. Setup

3.1. Installation

The iSnatch 49.6935.60 chronothermostat is designed for flush mounting into a standard 503 built-in electrical box. Ensure that power to the circuit is turned off at the main breaker before beginning installation.

  1. Carefully separate the control panel from the mounting base.
  2. Connect the electrical wiring from your heating/cooling system to the appropriate terminals on the base. Refer to the wiring diagram provided with the product packaging for specific connections.
  3. Secure the base into the 503 built-in box using the provided screws. Ensure it is flush with the wall surface.
  4. Once the base is securely mounted and wired, proceed to battery insertion.

3.2. Battery Insertion

The chronothermostat is battery-powered, requiring 3 Volts (typically 2x AA or AAA batteries, refer to the battery compartment for exact type). Proper battery insertion is crucial for operation.

  1. Locate the battery compartment on the back of the control panel.
  2. Insert the batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
  3. Once batteries are inserted, the display should illuminate, and the device will be ready for initial setup.
  4. Carefully reattach the control panel to the mounted base, ensuring it clicks securely into place.

4. Operating Instructions

4.1. Initial Power-On and Clock Setting

After battery insertion, the device will power on. You may need to set the current time and day.

  1. Press the SET button (5) to enter the settings menu.
  2. Use the Function Setting Buttons + (2) and - (9) to navigate to the clock setting (indicated by the TIME indicator (6)).
  3. Press OK / MANUAL (7) to confirm and adjust the hour, then minute, and finally the day of the week using the + (2) and - (9) buttons.
  4. Press OK / MANUAL (7) after each adjustment to move to the next setting.
  5. Press SET (5) to exit the settings menu.

4.2. Basic Temperature Adjustment (Manual Mode)

To manually set a desired temperature:

  1. Ensure the device is in manual mode (the Manual Temperature Override Indicator (13) may be visible, or the AUTO indicator (14) is off). If in automatic mode, press OK / MANUAL (7) to switch to manual.
  2. Press the TEMP button (6) or (19).
  3. Use the Function Setting Buttons + (2) and - (9) to adjust the desired temperature.
  4. The new temperature will be maintained until the next programmed event or until manually changed again.

4.3. Programming Automatic Operation

The chronothermostat allows for automatic temperature programming throughout the day and week.

  1. Press the PROG button (4) to enter programming mode (the PROG indicator (7) will appear).
  2. Use the SELECT button (3) to choose the day or group of days you wish to program.
  3. Use the + (2) and - (9) buttons to set the desired temperature for specific time blocks. The Program Profile Indicator (24-hour bar) (3) will help visualize the schedule.
  4. You can set different temperature levels: Comfort (16), Semi-Comfort (17), and Economy (18).
  5. Press OK / MANUAL (7) to confirm each setting and move to the next time block or day.
  6. The COPY button (8) or (20) can be used to copy a day's program to another day.
  7. Press PROG (4) again to exit programming mode. The AUTO indicator (14) should be visible, indicating automatic operation.

4.4. Special Modes

  • HOLD Mode (12): Press the HOLD / COPY button (8) to activate. This mode maintains a constant set temperature indefinitely, overriding the programmed schedule. Adjust the temperature using + (2) and - (9). Press HOLD / COPY (8) again to deactivate.
  • HOLIDAY Mode (11): This mode allows you to set a specific temperature for an extended period, useful when you are away. Consult the full product manual for detailed steps on setting the duration and temperature for Holiday Mode.
  • Antifreeze Mode (5): This mode automatically activates if the ambient temperature drops below a preset minimum (e.g., 5°C) to prevent pipes from freezing. This is typically an automatic safety feature.

4.5. Turning Off the Device

To turn off the chronothermostat, look for an OFF indicator (22) or a specific power button. If not present, removing the batteries will power down the device. Note that some models may have a standby mode rather than a full power-off.

5. Maintenance

5.1. Cleaning

To clean the chronothermostat, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture, as these can damage the device and its display.

5.2. Battery Replacement

When the Low Battery Indicator (15) appears on the display, it is time to replace the batteries. Prompt replacement ensures continuous operation and prevents loss of settings.

  1. Carefully detach the control panel from the mounting base.
  2. Remove the old batteries from the compartment.
  3. Insert new batteries of the correct type and voltage (e.g., 2x AA or AAA, 3 Volts), observing correct polarity.
  4. Reattach the control panel to the base. You may need to reset the clock and date after battery replacement.

6. Troubleshooting

  • Device not responding / Display blank: Check if batteries are correctly inserted and have sufficient charge. Replace batteries if the low battery indicator was present or if the device remains unresponsive.
  • Temperature not changing: Ensure the device is in the correct operating mode (e.g., not in OFF mode). Verify that the heating/cooling system is receiving the signal from the thermostat. Check wiring connections at the base.
  • Error message on display: If an error message appears, try removing the batteries for a few minutes and reinserting them to perform a soft reset. If the error persists, consult the manufacturer's support.
  • Inaccurate temperature readings: Ensure the chronothermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its internal sensor.
