To tailor the settings of your EPH CONTROLS R37-HW 3 Zone Programmer to your home's unique heating and hot water needs, follow these steps: First, access the settings by lowering the cover on the front of the programmer. This cover is secured by four hinges. Next, perform a master reset. Locate the small circular hole situated between the third and fourth hinges. Insert a ballpoint pen or similar tool into this hole to initiate the reset. Following the master reset, you will be prompted to reprogram the date and time. Once this is done, you can begin to customize the settings to your liking. This includes options such as program type (e.g., 5/2D), backlight adjustments, enabling or disabling the keypad lock, setting frost protection parameters, and selecting the clock type. Always prioritize safety. Ensure you adhere to all safety precautions outlined in the installation guide. Any modifications should be undertaken by a qualified professional in compliance with local wiring regulations.
