It shouldn't be so unexpected but sadly it is! How often do you find an entire piece of kit has to be replaced when one element has had its day? We needed a new programmer when our previous Honeywell ST699 of the grand old age of 30 years, began to play up. I was delighted to find the same product still available - and what a fantastic low price on Plumbworld! - and over the moon when I found that the newly purchased front section would fit the original back mount. All that was needed was to click the new front into place on the old back and hey presto - problem solved! What a joy!
This item was ordered to replace the original ST 699, which was suffering from a deceased back-up battery on the circuit board of the existing controller. Upon its arrival by first class post, it took me all of fifteen seconds to isolate, remove and replace the defective unit since it was fitted in the Honeywell surface mount connector backplate. It took longer to re-programme the timer than to actually remove and replace the unit! Excellent!
Replaced a faulty programmer that must have been over 21 years old, with this same model, I'm sure this one will last as long. Easy to order from the Plumbworld website, great price, cheaper then most places. The order came the next day, easy to fit, straight swap. We are nice and warm again, thank you.
Easy Peasy - Changing the unit from an eleven year old similar unit with a failed battery pack took less than one minute, aside from re-setting the time clock!
This controller does what it says on the tin. A direct replacement for a 25 year old which had eventually failed. I wont be here for another 25 years to review the next one.
