Greenhouse FAQs

GHK 12x2
Why won't the vent cycle work when I manually try to start it?

If the controller is in a cooling mode (i.e. the setpoint is below the current temperature and the cooling appliances are operating), the vent cycle will start and then shut off again.

Why won't the fans run when the controller goes to NITE mode and the temperature is above the set point temperature??

The controller could be in NITE Lock-out mode. To check the NITE Lock-out setting, press menu until ntLo is displayed. Press ENTER to see if NITE Lock-out is set to on or off. Press any number key to toggle the setting. Press ENTER to save it.

I'm adding natural ventilation to a house with a Bartlett GHK12X2 in it. Can I upgrade the controller to an RWL11X2 without completely replacing it?

Yes. Call us for assistance in changing out the current controller lid for that of an RWL11X2 lid for a small fee.

I can't find my manual for my greenhouse controller. Can I get a new one from Bartlett Instrument Company?

One option is to download a printable manual from this page, on our web site. Another option is to call us and order one to be sent to you. There is a nominal charge for this, however.

How do I use CIS to text me when I have a low or high temperature alarm in the greenhouse?

Setting up text alerts with CIS is easy. Click Options in the top left corner and in the drop down, click on Preferences. Click on the Messaging tab under preferences. At the bottom, enter the sender information, which can be any email address you'd like to use. The sender email can also be the receiving email for the alerts. Once you've entered that information, enter your phone number under Text Recipient, select your phone carrier from the drop down, and press the Add button. Press the Send Test Message button in the bottom left corner and you should get a test message sent to the phone number you have entered. If you receive an error, you've either entered the Sender or Text Recipient information incorrectly, or your computer is not connected to the Internet and it is unable to send.

Can a Wind/Rain alarm be connected to a VSmart controller?
