FP735Si Programmer is a three channel programmer providing outputs for controlling ON and OFF periods for room heating and hot water. Each output channel can operate independently of the others, having its own separate timing.

FP735Si is fully Part L compliant, and provides a single unit solution to fulfill the requirements for controlling a Hot Water zone together with two Room Heating zones.

FP735Si offers up to six “ON-to-OFF” or “OFF-to- ON” changes each day. Independently set for each zone.

Programming Modes

Several programming modes are available for selecting “ON” and “OFF” periods that completely suit the domestic needs. 7 day mode allows each day to be programmed individually. 5 day/2 day mode allows different “ON” and “OFF” periods to be set for the weekend.

Holiday

The FP735Si allows the user to switch off the Hot Water and the Heating for a programmed holiday period. When the end of holiday date has been reached, the Hot Water and Room Heating will return to normal operation settings.

Info

An information key allows quick viewing of product model number, software revision number, holiday end date, and service due date.

Move to Next Event

By a single key press, the user can force the programmer to immediately move to the next “ON- to-OFF” or “OFF-to-ON” event. Again, this is made independently for the individual Room Heating or the Hot Water zone.

+ Hour Override

FP735Si provides the user the ability to override the running program. By pressing a key the user can extend a current “ON” time by 1, 2, or 3 hours. Or switch on the selected channel, when an “OFF” period is active.

Service Interval Timer

The service interval timer allows the installer to select a service due date for the boiler, this can be set at between 28 days and 366 days from the current date.

Service due date is within 28 days

From 28 days prior to the service due date, a visual warning will appear in the display and a buzzer will sound for 30 seconds each hour commencing at midday. This can be cancelled for the current day by pressing any button.

Service due date is reached or passed

When the service due date is reached the visual and audible warning are repeated each hour of the day commencing at midday, but the duration of the alarm is increased to 60 seconds, this can be cancelled for the current day by pressing any button.

All override and programming buttons are disabled and depending upon service interval timer setting, heating can be restricted to 15, 30 or 45 minutes in each programmed hour.
