Modern design

CNS Trend and Plus are modern surface-mounted convection heaters. The sleek European slimline design works for stand-alone installation or makes an effective, efficient replacement for traditional baseboard heaters, accomplishing the same heating using significantly less room.

Naturally silent

CNS heaters use natural convection for draft-free operation. Cool room air flows in the bottom of the unit, is warmed by the heating element, and rises silently out the top to heat the room. The CNS is designed with a frost protection setting. The lowest thermostat setting will maintain an appropriately-sized room above freezing temperatures. Overheat protection is built in.

Heating flexibility

With its built-in thermostat, a single CNS is perfect as a stand-alone heating system in bathrooms or small rooms. Multiple CNS units can be placed strategically in larger spaces and their temperature settings adjusted individually for maximum comfort control. If desired, CNS Trend heaters may be wired to use a remote line voltage thermostat. Remote thermostats are not recommended for CNS Plus models.

Setting the date and time

In order to use the timer functions of the heater, the date and time need to be set first.


Setting Comfort Mode and Night Mode temperatures

Note: Night Mode is called "Setback mode" in this video. Night/setback Mode is the lower temperature part of a timer heating program. Comfort Mode is the higher temperature daytime part of a timer heating program. You may customize both your desired Comfort Mode (warmer temperature) and Night Mode (cooler temperature) settings. These selected temperatures will then be used when running any of the timer preset programs.


Choosing your heating timer preset program

Using a timer preset like "Pro1" in your home will save money and increase comfort by lowering the heater temperature automatically each night. Preset timer "Pro2" is designed for use in an office. In addition to turning the heater down each night, "Pro2" keeps the heater in Night Mode all weekend to maximize energy savings and avoid heating a space where people aren't present. "Pro3" is a totally user-customizable timer program. You can set the start and stop times for Comfort Mode and Night Mode individually for each day of the week.


Customizing Timer Program 1 (Pro1) and Program 2 (Pro2)

By default, Comfort Mode runs from 8:00 am to 10:00 pm each day. Night mode then runs from 10:00 pm to 8:00 am the next day. These start and stop times are easily changed in "Pro1" and "Pro 2" if desired.


Creating a custom timer program (Pro3)

Timer program "Pro3" allows you to set Comfort and Night Mode start and stop times separately for every day of the week.
