It is designed primarily for separate control of your heating and stored hot water (S or Y plan). 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.

Records the default button state of the corresponding category & the status of CCPA. It works only in coordination with the primary cookie. If there is no other Full UART, you can try wiring a Pull-up Resistor: Connect a Resistor (300 Ohm to 1k Ohm value; a lower value is more effective) between this UART's RX pad and either a 5v or 3.3v pad as shown below:

If it starts Blinking Slowly (500ms Blink Pattern), you will need to move the receiver wiring to a different UART.A C in the top-right corner should be visible indicating TX module and Receiver are connected and Communicating. A Receiver flashed or set with a Binding Phrase WILL NOT initiate Manual Binding mode, however many times you try the procedure below. You must first reflash the receiver with the Binding Phrase field disabled and/or unset. Why would you not use a bind phrase though if you're already having to flash the RX anyway? The ES2247B is a two channel multi purpose programmer with the flexibility of two or three on/off timings per day and can be configured for 7 day, 5/2 day or 24 hour operation for independent channels (all within the one unit), allowing one product to suit all installations alleviating any potential of incorrect selection.
