| Rion™ Greenhouse Window Opener |
| _____________________________________________________________ |
| This Rion™ Greenhouse Window Opener is solar powered. With the addition of this greenhouse accessory you can be sure of an even temperature in your greenhouse day and night. This unit is thermostatic controlled and provides continuous temperature control.The manufacturer recommends removing the cylinder during periods with frost as the openers may try to open the windows when the sun warms up the cylinders. If the windows are frozen, this may cause damage to the cylinder due to the need to release stored surplus energy. |
