Horstmann H27XL Programmer, Multi

Product Information

The default factory settings are shown, however if you wish to change these proceed as instructed below. 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 the Central heating and Hot water, however on a Gravity system the Central heating and Hot water are linked so that it is not possible to use the Central heating independently. This will allow only one common time setting for both Hot Water and Central Heating. BATTERY lt;p>This is the Horstmann CentaurPlus C27, a two channel programmer which gives independent control over hot water and heating with up to 3 ON/OFF settings for each day of the week. It also has a 1 hour manual boost button for the hot water and an advance button for the central heating.</p>

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.
