Comfort Zone Cz230er 7500-watt Digital Thermostat User Guide

Comfort Zone CZ230ER 7500-Watt Digital Thermostat

In a crowded warehouse, garage, or storage room, the fan-forced heater’s hard-wired installation and ceiling mounting conserve important floor space. The commercial heater’s body is made of strong gauge steel, which withstands temperature changes in inadequately insulated spaces well. The fan-forced design aids in evenly distributing the airflow throughout the space while louvres and a variable mounting angle direct it where it is most needed. With the help of a remote control, you can easily alter the settings from a distance while the digital thermostat lets you set the temperature to the ideal level for your room. When the interior of the ceiling mount heater overheats, a built-in sensor recognizes this and instantly turns the heater off.

FAQs

Does it come with hardware? If not, what size lag bolt is appropriate for ceiling stud?

Unit comes with ceiling mount bracket. 1, 3/8″x2″ Lag bolt through center mounting bracket hole, is sufficient for ceiling mount, provided material lag bolt is installed in a solid wood or better material.

Will it start and stop based on the thermostat? Not sure why a timer is needed if it shuts off when temp is reached.

Yes, it will. However, be aware that the internal thermostat housed within the unit will read a temperature that is higher than the room temperature and thus will shut off prior to the room reaching the set temperature. This could be remedied by wiring a room thermostat.

Can you set it to run continuously without the timer turning it off?

Yes

How long does it take to ship? Cold season almost over.

It fairly quickly and we love it

How many amp service do I need?

40 amp breaker. You only want to be at about 80% of total available power to keep things running smooth. The book on this unit actually recommends 50 amp but that’s an overkill.

What gauge wire does it require?

30 amp X 240v =7200 watts that’s running at max allowed. You should only be running at about 80%. 80% of 7200 =5760. This heater on low runs at 6250. So, no you need 40 amp breaker with 8/2 Romex wire

What is the dimensions of this heater? And could I install a plug on it instead of hard wiring it?

Mine has a dryer plug on the end and I plug into an outlet on the wall near the ceiling where the heater is mounted.

Does the 7500 watt have high medium low settings like the 5000 watt?

It has high setting at 7500w and low at 6250w

Would a double pole 30 amp be the same as 60 amp?

No, the wire gauge would be rated by the requirements you need to wire for the required device. You would need a double pole (240 volt) 40 amp breaker and assure the wire gauge used is #8 copper. Double pole 30 amp is under rated for this installation and double pole 60 amp is over rated.

My shop is 1200sq ft. with 20ft ceilings. I was looking at a 12,000 watt unit but would I be better with two of these 7500 watt units?

If it is of any help I have one 7500 watt unit in my 1800 sf insulated garage/shop with a 10 ft ceiling in NE Oregon. Very pleased so far with this heater. I have only used it on the 5000 watt setting and it does a good job of heating my shop. Seems a ceiling fan or two might be helpful.

What kind of plug does it come with or does it have to be hard wired?

Hard wired

Can you set this unit to a certain temp and have it keep the area that temp all winter without fussing with it?

This answer is for the manual control CZ220 with a dial. Someone else will have to speak for the CZ230. The answer for the CZ220 is: Well – kind of yes. While there is no specific temperature selection…. I was able to figure out by turning the dial.

Can you use this on the floor? I want to just set it down on a concrete floor.

This heater should have a minimum distance of 13 inches from a wall, and 6 feet from any floor.

I have a wood working shop. Would dust be problem for this heater.

This heater has hot and arcing parts inside and could be a fire hazard in a woodworking shop if placed in an area with a lot of wood dust.

I have a 30 amp hookup in the garage. Is this enough for this heater?

I sure a 30 amp dedicated circuit would work.
