Honeywell ST699

Product Information

The programming sequence for the ST699 is straightforward, using the top slider switch and [+] and ['] buttons. If your item is being delivered in the UK or Ireland, it will be delivered by UK Mail/DHL, Hermes or Royal Mail, with the exception of pallet items. So, for example, if you set your heating to come on at 5pm and go off at 10pm, but only want hot water on from 6pm to 7pm. Had a look at my wiring centre and the wiring for the two port ch valve doesn't appear to have a brown wire - it looks black! I suspect that the Red wire from terminal 8 on ST699 to terminal 4 on ST9400c may be the problem, but not absolutely sure which terminal it should go to on 9400c.

The front control unit has spring loaded contacts to the base plate, so you don't even need to do any rewiring.

We find the physical slider switches so much easier to use than having to press a couple of buttons repeatedly for the various functions.From the product page you can use Paypal Express Checkout which will take you straight to your Paypal account where you can login to complete payment or apply for Paypal Credit.
