How to reset Service Interval function on Siemens programmer?

coffeehound

The Siemens RWB1001 central heating programmer here has decided I'm not allowed to use the heating. Apparently it's the Service Interval timer which locks out normal use until it is reset, only allowing the 1-hour boost to work.

The user instructions online don't say how to reset it. I've tried the biro-actuated reset switch and turning the power off and on. Suppose the instructions are in the installation manual. Anyone know how to do this please?

I have same problem. Could you tell me how you sorted it.
Thanks

Unfortunately I didn't keep a copy of the instructions and thorganby's image file has expired. I've messaged him to ask if it's possible to post it again here. Or maybe someone else will answer first . .

• Open cover on upper RHS
• Move top slider to LHS (that should be a clock symbol)
• Press and hold 'REVIEW' button
• Whilst holding 'REVIEW' button, now press and hold '-' button
• Whilst holding both buttons, now press and hold 'YES' button
• Wait about 5 seconds, and a service screen should appear
• Release buttons, and now press 'YES' button. This confirms entry into the service menu
• You should now see the set service period e.g. 365d (d=days)
  The range can be set to a maximum of 400d
• Using the '+' or '-' buttons, adjust the period so that it reads 'OFF'. You will find this located between 400d and 1d.
• Press the 'YES' button twice to exit the service menu.
  (as you have turned the service interval function off, no need to set the pre-warn interval)
• Now move the top slider to the RHS (should be 'RUN')
• Close cover

Not sure why the "Classified" info was removed from the hosting site.

Simplified version.
