CT-CT-3P Controller w/4 Outlets

This controller also offers two thermostats for different day (light period) and night (dark period) temperatures plus CO2 override. When the temperature in your space reaches the set point, any CO2 enrichment equipment plugged into the left outlets is deactivated until exhaust functions are complete. In addition to switching the controller from day to night temperature settings, the on-board photo sensor defeats CO2 enrichment during periods of darkness. 115V 15amp with an operating temperature of 32-120 degrees F.
