Product Information

This document is to be left with the user and forms part of a Home Information Pack WHAT IS A PROGRAMMER? T echnologies Sarl, Ecublens, Route du Bois 37, Switzerland by its Authorised Representative Honeywell Inc. They mention that it is easy to program and operate, changing the settings was delightfully easy, and that the controls are easy to read and set. In the evening, when the house is up to temperature, it is often possible to switch off the heating up to an hour before you go to bed, without any noticeable reduction in comfort.

The unit has independent controls to Override the time switch setting (turn On when Off or Off when On) and also Boost to just give 1 - 3 hours extra On time.The clock can be reset easy, the problem is the instruction book fails to mention that the controls to do so are under a simple hinged drop down cover on the front of the unit, then follow the instruction book. In the Winter the Central Heating is set to Once a day (the Heating being controlled by the room state) - early morning to late at night, the Hot Water remains on its Auto setting.

We're sorry but this product has now been discontinued by Honeywell Heating Supplies and can no longer be purchased. The unit came with the time and date already set, it had also been programmed, so it was ready to go. All Honeywell ST9400 models incorporate the Line of Text (LoT™) display that gives clear plain English instructions whenever any button or slider is used.

They mention that the programming is clear and concise, and the pre-installed settings are very sensible and similar to what they would normally use.
