Programmer clicking and flashing

[G1nzo]

Have a Danfoss FP715 Programmer fitted
about 12 years old
Works O.K when just Central heating on but when the HotWater came on Automatically at 6pm both the Leds flash and the unit clicls loudly
also the Pump stops and starts quickly
running either the Central heating or the Water on their own is fine

I Have reset the unit but its the same
Is this a sign of a Faulty Programmer ?
if so is what would be a direct replacement for this unit

Is this a sign of a Faulty Programmer ?

Certainly looks that way
AFAIK FP 715 is still available

Would the FP 715 si be a direct replacement
ie would the back panel wiring connections be the same

The wallplate used follows the industry standard pattern, as used by many of the other time control Manufacturer's. This allows for direct replacement often without the need for re-wiring.

If its the same basic model number I cant see them changing the wiring but if they have done the instructions will see you through.
