Honeywell question

Newbie here.
Installed a Honeywell TH8320WF on a two wire powerpile steam boiler. I think my install is correct as I added a 24v transformer for the C wire and the boiler kicks on. Howerever in the setup I can't access function 0170 to select option 3 which is for "heat only without fan".
In the setup process it goes from function 0165 to 0280 bypassing everything in between. I would like to access this function as the default is set for heat/cooling air pump. I only need the heat only option and the cycle rate for "Gas/oil steam or gravity system" which is option 0240.
Any help would be appreciated.
Thanks

Welcome to the forums.

If you don't see all the setting numbers then you are in thermostat setup not installer setup.
Actually.... 170 should be set to 3 for two wire heat only.

Oops ...now noticed that in installer manual. I was referencing the user manual which says to press the middle blank key not the two blank keys on either side of middle key. Will try now and report back. Thanks

Success. Was able to apply correct settings for heat only and gravity steam.
Thanks PJmax.
