Passive Cooling

Side Vents
Roof Vents
Roll Up Curtains

By using the stadnard outputs in the Ventmate Plus, any morotized vent system or curtain roll up system can be opend in up to ieght stages without the need for any external limit switches. Changing position openings can be done in seconds from the front panel. All passive outputs feature adjustabe time delays, temperature spans and differentials. Up to two series or sets of vents can be controlled.

Air Circulation

Hortizontal Air Flow Fans / Fan Jets

The Ventmate Plus features air circulation capabilities that can operate any equipment to turn on or off in relation to a vent stage.

Active Heating

Gas fired Heaters
Hot water zone Valves

The Ventmate Plus system will operate any active heating equipment in maintained stages of operation. Two separate temperature setting can be enters for all equipment. Day and Night Modes are standard. All active outputs feature adjustable time delays, temperature spans and differentials.

Special Feature

RH - dehumidification

The inclusion of this special feature sets the Ventmate Plus far apart from standard greenhouse control systems. The addition of a true digital humidity sensor allows the grower to monitor the humidity level and dehumidify the greenhouse if needed. The Growmate Plus will also recall the highest and lowest temperature and humdity level for the previous 24 hour period.
