Features

THC series Temperature and Humidity Controllers are designed for intelligent control of standard dry-contact operated HVAC systems plus dehumidifiers in growing environments. Featuring advanced reheat and external humidity control options that are unique to indoor agriculture. Operate heating, cooling, reversing valves, reheat dehumidification, and standard humidity equipment using 24VAC control.

Integration with GrowControl GCX Systems
Connects to GrowControl™ GCX Cultivation Control Systems for operation from a central controller.

  • Monitor, log, and graph the THC’s temperature and humidity data.
  • Operate from an external canopy sensor instead of the internal sensor.
  • Schedule changes to the set points.

Backup Power and Stand-Alone Operation
The THC controller can operate off of the HVAC system’s 24VAC power source to continue operating in the event that the main control system becomes disconnected or loses power. The integrated temperature/humidity sensor, on-board clock, and internally stored set points allow the unit to seamlessly continue operating and controlling the environment.

AGROWtEK Temperature Humidity Controller - Features

Simple Operation, Powerful Control
LCD display shows local temperature and humidity, output status, time/date, and more. Settings are configured quickly and easily via the button-driven menus or from the master GrowControl™ GCX controller.
Easy installation with a reversible mounting plate for junction box installation or flush wall mounting and bottom cable entry where a junction box is not available. Standard terminal block wiring connections.

GCX System Integration

The THC can operate stand-alone like a traditional thermostat, or it can be integrated with a GrowControl™ GCX facility control system.

AGROWtEK Temperature Humidity Controller - GCX System Integration

Central Monitoring
When connected to a GCX, the THC controller will report back the current sensor readings and status of each contact for data logging and real-time monitoring in the room dashboard.
Contacts can also be manually forced on or off for maintenance from the GCX interface.

AGROWtEK Temperature Humidity Controller - Central Monitoring

Scheduled Set Point Changes
The GCX controller can send updated set points and sun-rise/sun-set times on any schedule to automate changes in the room environment set points. Easily manage the set points for each room or zone from the GCX system.

AGROWtEK Temperature Humidity Controller - Mount the Wall Plate

warning NOTICE
Do not over-tighten the cover screws or junction box screws to avoid bending the aluminum enclosure.

Prepare Connections

Connections consist of low-voltage control signals for HVAC and dehumidifiers, and an RJ-45 cable for connection to a GrowControl™ GCX Cultivation Control System.

GrowNET™ Connection (RJ-45/CAT5)
Connection to a master controller is optional, but it provides advanced control features described in the features section. Connection is made with a standard RJ-45 type connection and CAT5 or better cable. Standard Ethernet cables can be purchased from retailers if you prefer not to crimp custom cables.

HVAC System Connections (4, 5, 6, or 7-Wire)
HVAC connections include 24VAC (R), Common (C), and additional signals. The HVAC system provides backup power to the unit in the event that the GrowNET™ cable is not connected. See the example connections in the example wiring diagrams to determine thermostat cable wiring requirements.

Humidity Output Connection (2-Wire)
The humidity output is a single dry-contact that can be programmed to operate a humidifier or a dehumidifier. See connection examples in the example wiring diagrams; use two-conductor thermostat cable.

AGROWtEK Temperature Humidity Controller - Humidity Output Connection

Cable Routing
Low-voltage and GrowNET™ cables can be routed through conduit using a standard junction box mounting or through the bottom openings if no junction box is used (see wall plate mounting instructions.)

warning NOTICE
Ensure cables are routed on the terminal block side of the enclosure and do not damage or short into any components on the PCB.

HVAC Wiring

Standard HVAC systems provide 24VAC power from the system’s transformer, which acts as a backup power source when connected to a GCX system, or as a primary power source when used stand-alone. The 24VAC is also switched by onboard relays (contacts) to the HVAC system’s demand signals in order to operate the unit.

Conductors required according to HVAC system stages:

System Type Signals Conductors
Single Stage AC Only R, C, G, Y1 4
Single Stage AC, Single Stage Heat R, C, G, Y1, W1 5
Dual Stage AC, Single Stage Heat R, C, G, Y1, Y2, W1 6
Dual Stage AC, Dual Stage Heat R, C, G, Y1, Y2, W1, W2 7

Connect the HVAC system signals according to the labeling on the PCB and the diagram below.

AGROWtEK Temperature Humidity Controller - HVAC Wiring

Humidifier/Dehumidifier Wiring

The THC controller is capable of operating either a humidifier or a dehumidifier from the dry-contact output.
The humidifier or dehumidifier must be compatible with low-voltage control.

Standard dehumidifiers manufactured by common brands such as Quest and Anden typically have a low- voltage external control connection for 24VAC control signals similar to an HVAC system. Units can be daisy- chained from unit to unit according to the manufacturer’s instructions.

AGROWtEK Temperature Humidity Controller - Symbol 1 NOTE
Depending on how the THC is configured in the Config Menu, certain menus or menu items may or may not be available to the user. Only the relevant menu items will be displayed.

Set Points
Day & Night Set Points
The THC unit features internal set points for temperature and humidity with independent values for day and night. The day and night periods are configured in the Time menu; see sunrise and sunset times. These set points and times can be automatically updated based on a grow schedule when connected to a GrowControl™ GCX control system.

Set Point Off sets
Offsets determine when the heating and cooling (or humidification and dehumidification) stages begin and end relative to the set point.

End Mode
Determines if the second stage of heating, cooling, or dehumidification ends at the set point (on target) or at the off set (staged)

Mode Description
Staged Stage 2 turns off at the stage 1 offset.
On Target Stage 2 turns off at the target set point.

HVAC Control

The THC is designed to install and operate like a standard dry-contact wall thermostat and can handle various types of systems, including gas or electric forced air, boilers, and heat pumps (see Config Menu)
The THC supports up to two stages of heating and two stages of cooling with fan control.

AGROWtEK Temperature Humidity Controller - Symbol 1 NOTE
When configured for reheat control, stage 1 or stage 2 heating contact is used; see the reheat section.

Humidity Control

The THC has a dedicated humidity control output contact, which can be configured for either humidification or de-humidification (default). The humidity contact is typically used to operate dehumidifiers in a growing space in coordination with standard HVAC equipment.
In addition to the humidity contact, the controller can also operate a reheat contact in order to dehumidify the space. See the reheat section for additional detail.

AGROWtEK Temperature Humidity Controller - Symbol 1 NOTE
Two stages of dehumidification are available when reheat is enabled, and the humidity contact is configured for dehumidification.

Reheat Dehumidification

Two types of Reheat dehumidification systems are supported by the THC: standard and economy.

Standard Reheat
Uses output W2 (heat 2) to activate a reheat stage, and the output Y1 (compressor 1) to activate the compressor when dehumidification is required.
Reheat turns off If cooling or heating is demanded due to the temperature in the space.

Economy Reheat
Uses output W1 (heat 1) to activate a heat stage, and the output Y1 (compressor 1) to activate the compressor when dehumidification is required. Reheat turns off if cooling or heating is demanded due to the temperature in the space.

Connection to GrowControl™ GCX

All GrowNET™ devices are connected using standard CAT5 Ethernet cable with RJ-45 connections.

Devices can be connected directly to the GrowNET™ ports on the bottom of the controller, or through HX8 GrowNET™ hubs. It is typical to simplify cabling by locating hubs centrally in hallways and rooms, allowing single runs from an 8-port device hub back to a central hub or back to the controller.

AGROWtEK Temperature Humidity Controller - Connection to GrowControl™ GCX

Refer to the GCX controller manual for details on adding the device to the system.

GrowNET™ Hubs

HX8 GrowNET ™ hubs expand a single port into eight more ports.
Hubs can be daisy-chained to form a network of up to 100 devices per GrowNET™ bus. Individually buffered port transceivers provide excellent signal integrity and extended communication strength and range.

AGROWtEK Temperature Humidity Controller - GrowNET™ Hubs

Hubs provide up to 1A of power for operating sensors and most relays directly over the CAT5 cable. A DC jack on the hub provides 24Vdc power to the ports from the included wall power supply. A terminal block power option is also available.

Easy THC Configuration

GrowControl™ GCX control systems integrate seamlessly with the THC.
Manage all of the configuration options from the controller without having to navigate the LCD menus.
