A corrosion-resistant, solar powered
piston extends to open and close greenhouse vents automatically.
Piston wax expands and contracts adjusting the vent as temperatures change. Most
openers support up to 15 lbs. (Below is a general sample instruction for the thermofor solar vent opener
- this example not be an exact match with your current vent
opener).

ADJUSTMENT (REF)
After allowing the solar
vent opener unit to reach the temperature at which you require
the window to start opening hold the window slightly open and
firmly turn the adjusting screw see fig. 4, in the direction of
the LO arrow (clockwise) until the unit begins to support the window
without assistance. Any rise in greenhouse temperature will now
cause the window to open wider. Further adjustment may be necessary
in which case repeat the process being sure to take the weight off
the unit, by hand, as before. Turning the adjusting screw in the
direction of the LO arrow (clockwise) starts the window opening at a
lower temperature. Turning the adjusting screw in the direction of
the HI arrow (anti-clockwise) starts the window opening at a higher
temperature.
PLEASE NOTE: ADJUSTMENT CANNOT BE MADE WITH THE
WEIGHT OF THE WINDOW ACTING ON THE UNIT. As the cylinder is
positioned to allow it also to sense the cooling effects of any
chilling air from outside the unit will automatically react and
adjust the window accordingly for added protection to your plants.
Will open window up to
37-1/2 cm (15") Opening temperature can be set between 15 deg C
to 25 deg C (59 deg F to 77 deg F) Will lift up to 7kg (15lbs)
WINTER USAGE: The solar vent openers use a waxy
proprietary substance in the vent cylinder. When it is warm, the
material expands and contracts to move the vent arm. If it is to
cold, the cylinder will not move and in some cases freezing and
thawing can cause damage to the unit.
