About this deal

On Sunday morning I was looking forward to a lazy few hours in my PJs. The plan called for a hearty breakfast, freshly ground coffee, some light reading and a hot shower before deciding what to do for the reminder of the day. Regrettably, the unexpectedly cold water from the showerhead put an end to an otherwise agreeable time. The programmer is fitted with a non-rechargeable, long life battery, which will maintain the programmed time settings for a minimum of ten months with the supply disconnected.

Using the RESET procedure may rectify the fault. If the problem persists the programmer will need replacing.During power interruptions the display will be blank, after 3 days the current time of day will be lost. If the programmer is not to be used for a long period of time, the switch on the rear of the unit should be returned to the BATTERY OFF position. These are both to prolong the battery life. SERVICE AND REPAIR I am wondering if the stand-off comes away from the main unit. I can pull the main unit away from the stand-off enough to get a screwdriver into the gap but it's not coming away consistently - only where I exert pressure so much that the plastic deforms.

Of course if HW is selected and not satisfied, the boiler/pump will run, because the power is supplied through the cylinder stat and not the valves orange wire. The simple instructions below are designed to help with the programming of the unit. All the following instructions require the front flap to be lowered. Please replace the flap when normal operation is required. SETTING DAY AND TIME OF DAYOn the ChannelPlus display - Boost 1 is Hot water extension 1 or 2 hour and Boost 2 is Heating extension 1 or 2 hours ADVANCE FUNCTION This indicates that you have reached an existing set time period, you will be unable to set a new ON/OFF time unless there is an alteration to the existing timed period The Secure Meters Horstmann CHANNELPLUS H27XL is a white 2 channel 7 day electronic digital programmer with independent timing of heating and hot water.. User friendly, it is designed for domestic use, providing advanced, easily programmed features. By pulling outward and generally downward I can clearly see the single wall box because I am dragging that towards me too. It is not separating from the main unit or the stand-off.
