Yes it is.

Our ST9400C was installed with a wireless DT92E thermostat but all the manuals on the ST9400C suggest it doesn't communicate with a wireless thermostat. Is the ST9400C able to communicate with the DT92E? Answers1

Only the ST9420C model will communicate directly with the DT92E. The ST9400C will require a separate receiver to be installed either by the programmer or by the wiring centre.

I'm afraid there is no direct replacement. You will need to change the complete control system.

I currently have an Honeywell ST699 controller, but would like to replace it with the ST9400C 7day programmer. Is it straightforward to change the unit, or does it involve some complex re-wiring? Thank You Answers1

It will connect to the existing wires. I would recommend labeling the wires and referring to the included wiring conversion guide to convert to the new terminal numbers.

Hi have a controller st6450 which has become unreliable switch on off. Would the st9400c fit the back plate? So no rewiring required. Thanks Answers1

Hi. Yes it would. A very simple DIY swap.

Hiya on our model the hot water and heating modes seem to have been changed so that the ‘hot water’ setting in fact doesn’t control hot water but controls another heating zone thermostat. Is that meant to be the case? Answers1

Hi. Normally the ST9500C is used as that is labelled correctly as heating 1 and heating 2 instead of heating and hot water. However the ST9500C is more expensive than the ST9400C.
