Continue to do this until the timer fits securely against the wall. 5. Remove terminal cover (D) by undoing screw (C). Insert the second No.6 screw into slot (B) and tighten. 6. Your timer is now ready for wiring. 1. Your GreenBrook Electronic Immersion Heater Timer should be wired from a fused spur. We recommend a PowerBreaker H92 model.

Pre-set programme times will remain unaffected. SWITCH During those occasions when you are at home early and you do not want your timer to be turned on or you want to make temporary changes to the programme setting, pressing button (H) will perform the following role depending on what is displayed on the screen display, e.g. Temporarily on, will stay on until next off setting.

Pressing prog button (B) will allow you to step through each of the settings, changes can be made at any stage by pressing the appropriate (F) hour and (E) minute buttons. 2. It is important to ensure the”on” days correspond with the ”off”days and that they do not overlap. 3.
