Systems
Wadsworth's
STEP 50A and STEP 500 climate controllers make the heating and cooling
equipment in your greenhouse work together. They help you save energy
and create ideal growing conditions for your crop. When your greenhouse
is too hot or too cold these controllers react gradually. They operate
just enough equipment to bring temperatures back in line. Both controllers
offer seperate day and night temperature settings.
The
STEP 50A and STEP 500 controllers let you maintain a "single,
total environmental program."
| STEP
50A |
The
STEP 50A is the sensible choice for greenhouses under an acre
with one or two vents. With its three cooling stages, you
can easily integrate three stages of fan and a vent that opens
and closes in three steps.
|
- Independent
day and night temperature settings and programmable cooling
lockout disables all or part of cooling at night.
- Two
stages of heating and three stages of cooling to save energy.
- Provides
a modulating output voltage for proportional steam and hot
water valves.
- After
a power failure, all equipment is off, comes on gradually
to controll temperature.
- All
stages have a color coded manual override switch and a pilot
light.
- Includes
an aspirated temperature sensor to read true air temperature
and a 10 Amp DPDT load relay for each stage.
- Locking
door secures settings.
- Corrosion

| STEP
500 |
For
growers with larger environments or more equipment, the STEP
500 adds two more cooling stages and an additional stage of
heat. |
- Independent
day and night temperature settings and programmable cooling
lockout with outdoor sensor, disables all or part of your
cooling on cold nights.
- Three
stages of heating and five stages of cooling to save energy
and adapt to sophisticated modern greenhouses.
- Digital
meter shows greenhouse temperature.
- Provides
a modulating output voltage for proportional steam and hot
water valves.
- After
a power failure, all equipment is off, comes on gradually
to controll temperature.
- All
stages have a color coded manual override switch and a pilot
light.
- Includes
an aspirated temperature sensor to read true air temperature
and a 10 Amp DPDT load relay for each stage.
- Locking
door secures settings.
- Corrosion
