Question 1

Some reviews indicate it limits the cycling of the system, but I don't find anything in the product description or online to verify that.

Accepted Answer

It will depend on the application your  thermostat  is hooked up to. Mine is hooked up to an oil/hot water furnace and does not restrict cycling. Cannot provide information should this be hooked up to another type of heating system.

Question 2

Can you adjust the themometer part if the correct temp is not being displayed

Accepted Answer

no, there is no way to "re-calibrate" the display temp if it doesn't seem correct

Question 3

can someone tell me if this can replace Robertshaw 8425-2 heat/2 cool ?

Accepted Answer

Your Robertshaw thermostat has 10 wire terminals and the Honeywell has 9 terminals. According to the Honeywell instructions, it will handle 2 stage heating and one stage cooling; or 1 stage heating and 1 stage cooling. You can call honeywell customer service to see for sure: 1-800-468-1502 ... that is the number on the instructions.From what I can see in the directions, the thermostat was designed to handle a wide range of heating (gas, oil, electric, hot water and steam) systems and air conditioning. There are several wiring options depending on the systems you have, so READ the directions prior to starting and follow them during the instalation.My thermostat is NOT cheap Chinese plastic, it was assembled in Mexico. It has worked very well for heating my home last winter and was working fine for cooling last week .... we are colder again this week! It is much more accurate than the programable Honeywell thermostat it replaced.

Question 4

Can this replace a Honeywell old 80's style heat only dial?

Accepted Answer

Yes. All you have to do is simply not connect any AC wires to the terminal. When you remove the old thermostat, take note of what wires went to what terminals, and try to duplicate. The instruction sheet will make it clear failing that.
(We have no AC, so we had the exact same situation.)
