ESi Single-Channel Electronic Timeswitch - ES1247B Overview
This ESi single-channel timeswitch is designed primarily for timed control of your heating and hot water.
It's well-suited for use with a combination boiler or a single heating zone. It can also be used in conjunction with an existing programmer to control additional heating zones or for when additional hot water cylinder control is required.
Functions and Design
This timeswitch comes with time and date pre-set and automatic summer/winter time adjustments.
The factory-set program suits most households but is quick and easy to adapt, making this a simple programmer to install and leave to do its job with little or no interaction.
The blue back light on the programmer can be switched permanently on or off, depending on the user's preference.
When the back light is off, it can be lit at the push of a button and will then turn off again. The programmer can be configured for 24-hour, 5/2-day or 7-day operation, and it has the flexibility of up to three on/off timings per day.
Picking the right type of Heating Control is an important decision. When you decide that Programmers & Time Switches are the best answer then the ESi Controls ES1247B is doubtless worth putting on the shortlist.
