The ESi Controls 2 Channel Programmer offers flexibility and reliability for use in any domestic heating and hot water installation. The ES2247B is a twin channel multi-purpose programmer, designed for the separate control of your heating and stored hot water. The heating and hot water programmes are independent of each other, giving you the opportunity to operate the system in the most energy efficient and cost effective manner. The industry standard back plate makes installation quick and easy, with time and date pre-set and automatic summer/winter time adjustment. While the factory-set programme suits most households it is quick and very 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 has the flexibility of up to three on/off timings per day.
