The following are some of the easy to operate features:-

Flexible 7 Day Control

1 or 2 Hour Boost on each channel

Independent timing on Zone 1 and Zone 2

Advance control gives instant On/Off override

Up to 3 On/Off periods per channel in each 24 Hr operation.

Programme options: Auto / All day / On constantly / Off

FULLY PUMPED OR GRAVITY SYSTEM

The installer will have set the programmer to suit the installed system. If this is a Fully pumped

system this will allow independent control of Zone 1 and Zone 2, however on a Gravity system Zone 1

and zone 2 are linked so that it is not possible to use Zone 2 independently. This will allow only one

common time setting for both Zone 1 and Zone 2.

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.

THIS SHOULD BE SUFFICIENT TO COVER POWER INTERRUPTIONS DURING THE LIFE OF THE UNIT.

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 BATTERYOFF position. These are both to prolong the battery life.

Horstmann’s ChannelPlus H27ZXL - Two Channel Programmer Offers up to

three programmed operating periods per day, seven days a week, with

independent Boost and Advance control on Fully Pumped Systems.

INFORMATION AND ADVICE

Programming ON/OFF times

If a Zone 1 or Zone 2 period is not required it can be cancelled by setting the ON and OFF

settings to the same time. Example ON 10:00am OFF 10:00am

Your programmer will prevent you from accidentally overlapping ON and OFF times.

Example: If the 2nd ON time is set at 12:00pm and then you try and set the 1st OFF at 12:30 pm the

OFF setting will ‘bounce’ by a 10 minute period until the 2nd ON time has been adjusted.
