To tailor the operation of your EPH CONTROLS R37-HW 3 Zone Programmer to your specific needs, follow these steps:
- Accessing the Settings: Begin by lowering the cover on the front of the programmer. This cover is held in place by four hinges.
- Master Reset: Locate the small circular hole situated between the third and fourth hinges. Use a ballpoint pen or a similar slender object to initiate a master reset. This action will restore the programmer to its factory default settings.
- Reprogramming: Following the master reset, you'll need to reprogram the date and time. This ensures the programmer operates with the correct time information.
- Customizing Settings: With the date and time set, you can now personalize various settings. These include selecting the program type (such as 5/2D), adjusting backlight preferences, enabling or disabling the keypad lock, configuring frost protection, and choosing the clock type. Modify these settings to match your desired heating and hot water schedule.
- Important Safety Note: Always adhere to the safety precautions outlined in the EPH CONTROLS R37-HW 3 Zone Programmer Installation Guide. Any modifications should be performed by a qualified individual, in compliance with all relevant national wiring regulations. For comprehensive guidance or assistance, consult the installation guide that accompanied your product or reach out to EPH Controls technical support via their provided email addresses or website.
