Honeywell DT90E and ST9400C

[nofuse]

I am looking to replace my honewell T6360B stat with a DT90E, I wish to use the built in frost protection of the DT90E but can I still use the programming features such as 3 on/off cycles and holiday mode of the ST9400C? as I seem to remember reading somewhere that to use the DT90E the programmer needs to be set to override.

Thanks

DT90E is not programmable (which you'd o/ride clock for), just a roomstat. It only differs from your old one in the following ways.

- Display & switching is battery powered, hence 2 wire connection
- Digital display
- On/Off switch
- Economy feature enabling you to set a temperature for 1 - 24hrs eg. if you're away overnight and want a minimum temp set.

All your timings remain through the programmer.

Basically what I want to know is if I still use my programmer for timed switching or the holiday feature would the frost protection of the DT90E still work in these modes?
