Harvest Master Quad and Tri Band Text Me GSM Modem

The Harvest Master GSM 'Text Me' Modem gives you instant text message updates, direct to your phone. Simply connect the Modem to any of the PLUS controllers and fully utilise the additional 8 in/outputs these controllers provide.

The Text Me GSM Modem will send 'status' updates, to get an update from your Harvest-Master controller from anywhere! You can trigger the updates by texting the unit with your requirments.

Turn the extra 8 outputs on your PRO or PRO PLUS model ON or OFF by text message. 

Get text messages for an alarm! Overheating, low water/fluid levels, or INTRUDERS! (door/window switches, motion detectors).

The GSM modem is can be used with the Plus Climate Controller. 

Configure the system so it operates a remote control on the 8 'extra' outputs.

Harvest Master CO2 Upgrade Pack for the Climate and PRO Models, make your standard system work with CO2

CO2 sensor upgrades the controller to monitoring and accurate dispensing of CO2 (to 100ppm). 

Harvest-Master knows when CO2 is operating and changes automatically to suit the high CO2 environment (higher humidity, no fans etc). 

Harvest Master can continuously relearn the "delivery time" required to get perfect ppm levels without overruns! 

Harvest-Master Automatically disables CO2 operations if the system runs out of CO2 (allows fans to be used and holds humidity to lower levels)!

Measurement Range: 0-2500ppm CO2
Measurement Resolution: 10ppm
Measurement Accuracy: +/- 100ppm
Operating Temperature Range: 0-50 Deg C
Operating Humidity Range: 0-95% RH 

Harvest Master Relays and RCA Modules allows your system to grow with you!

The Harvest Master systems work using RCA plugs to trigger devices or take in device data from trigger points you select.

Using the RCA Multi adaptor you can make a single inlet/outlet a 4 way outlet. Alternatively, use another one and daisy-chain together to make it a 7 way outlet, each one operating its own relay (12 amps), which in turn operate lights, fans, air-conditioners etc. The only limit is your imagination (up to a point given you need an electricity supply that will support your ambitions of course!).

The 240v 12amp Relays plug in to the mains and are triggered on/off using the RCA's above. Each relay should be plugged in to it's own source of energy, to avoid overloading your mains supply and circuit maximums.

Always get a suitably qualified person to install mains electricity circuits.
