Thermostat

I have a Carrier heat pump system with a 2nd stage oil furnace backup. No problem with the main progammable thermostat. Problem is the thermostat in basement that controls the point at which the heat pump shuts down and oil backup comes on is an old Carrier Energy Optimizer Control that no longer works properly. It has an outdoor temp sensor connected to a solid copper wire that runs through the wall to the outside and can be set at the optimal temp where the heat pump is no longer efficient. I would like to replace this control with a non programmable digital thermostat with an wireless outdoor temp sensor. Any products to recommend?

these are AAON package, rooftop units used to control the environment of the hallways on 4 floors of a hotel. there are two units, one east, one west. these temp controllers are mounted in the ceiling tiles of the 4th floor. they don't look or function like an average thermostat. these look like they are built onto the back of a standard wall switch plate. on the exposed side, there is a simple slide switch marked "warmer" on one end and "colder" on the other end, there is a midway mark as well. there are no fan switches, or any scale for a temp setting. are you familiar with this type of temp controller, can you give me any info

oochie,

Look item # 4LWX6 on page 4217 and item # 4JZ60, 4JZ61 or 3T186 on page 944.
You will set the temperature alarm warmer that what you use, so if the temperature raise will active alarm. I keep freezer at 0f my alarm is at 20f. so I have time to see what happen before the food melt.

Answers

Answer: 
jrod,
For a Definite Purposed Contactor, like the one you may have, look how many poles, inductive amp and coil voltage. If you don't know, look the label on your contactor this information is there. You may have a 1+ pole, 40 amp (inductive), 24 Volt coil. I know because for this size the unit it's what you usually have. Get the information look the Grainger catalog page 334, if you see one similar and call Grainger. Do NOT install a contactor with less amp that the one you have. There is not a rule to how cross reference for a contactor, I'm doing HVAC & R for 15 years.
