The GCP-12 controller is a multi-function environmental control system. This model features 4 independent timers for HID / LED control, each one is assigned to a single 220 or 120 VAC output.

The 12 independent 120 VAC outputs can be assigned to activate fans, blowers, air conditioner units or CO2 generator / valve. Multiple functions can be programmed based on temperature, humidity or CO2. As an example, outlet 1 and 2 could be programmed to energize on a temperature limit while outputs 2 and 3 could energize on a low CO2 condition.
Comes Complete With:

  • (1) GCP-HTC Sensor Module
  • (1) 20' Cable with connectors
  • (1) 220 VAC 4 Blade Cord or (1) 120 VAC Cord
