Hi all,

This may have been covered before, but I found nothing in a search.

I had to replace an old thermostat last year (Taco), so I replaced it
with a Honeywell FocusPro TH6110D. It is easy to program and operate.
The unit was installed by my heating contractor.

Problem #1. contractor left all settings at factory settings. I
noticed last year that the zone controlled by this thermostat were
cold. Forgot about this in the spring and now that we're heating
again, the problem is still here. I talked to Honeywell and changed
the settings to match my system (changed to the correct heating cycles
per hour). I have forced hot water (baseboard) and an oil fired
boiler. A zone valve on each heating loop. 24V system.

Problem #2. Thermostat calls for heat only about every 1.5 to 2 hrs.
Apparently the thermostat only responds to the temp change (2
degrees ; +/- 1F).

Question: Am I correct in assuming that the CPH setting is equivalent
to the anticipator in the old thermostats?

How should this CPH setting work? Is the thermostat supposed to call
for heat a number of times an hour in order to reduce the large temp
swing?

I hate to call the contractor, only because of the cost per visit.
They will give me some info over the phone.

Anybody dealt with this before?

Thanks for the help.
