The GCP-4 controller is a multi-function environmental control system. This model
features 4 independent 120VAC outputs and 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.
The GCP-4, our smallest system is suitable for smaller, single room growers.
