| For the basics in garden room
control the 24-CT-1 might be
just what you need. This handy
item incorporates two of the
more common requirements of
a small enclosure. A timed outlet
and a thermostatically controlled
outlet. This unit is ideal for
operating lighting, CO2 equipment,
watering systems, fans etc.
and provides an economical solution
for many greenhouse control
needs. |
|
 |
| To set the timer, turn the
dial to current time of day.
The dial face is divided into
15 minute increments. Rotation
is clockwise only. To have the
timer come on at specific intervals
push the black tripper switches
toward the center of the dial
for the "On" periods desired.
The thermostat is used to operate
cooling equipment and is sensitive
to temperature rise. The internal
sensors will allow a 7 degree
comfort zone. Set the dial to
the maximum temperature that
you want in your growing area
( Ideal temperature + 7 degrees
) . When temperature increases
to this setting the "Exhaust
Equipment Outlet" ( right outlet
) will activate. These outlets
operate independently and neither
one defeats the other. Operates
on 110VAC with 15 Amp switching
capacity. |
|
| Used independently as shown
above this dual function controller
will perform two of the most
essential requirements of an
automated system. Available
with remote bulb heating thermostat
( 24-HT-1X ) for propagation
bed heating and lighting control.
Do not exceed 15 Amp combined
power draw. |
|
| By using Green Air Products
High Amperage Relay ( HAR-1)
high voltage or amperage draw
equipment can be functioned
with the precise accuracy provided
by the 24-CT-1 |
|
| In this
example the 24 hour clock timer
will limit the CO2
cycles to desired hours by defeating
the CST-1 timer. The cooling
thermostat will function exhaust
fan according to temperature
fluctuations. External coil
or remote bulb sensors are optional. |
|
| The internal temperature sensor
installed in this controller
has been calibrated and should
not require further adjustment.
The thermostat may be calibrated
with trim screw through hole
provided on dial face under
the set point knob. Avoid undue
pressure on trim screw. Adjustments
are very slight and 1/8 turn
either way is usually adequate.
Place thermometer next to controller
and let it stabilize to ambient
temperature. Unplug fans or
CO2 equipment from controller
during this procedure. The controller
should remain plugged in with
switch "on". Outlet light will
indicate switch points. Turn
thermostat knob to the left
until exhaust outlet indicator
light comes "on". Slowly turn
knob back to the right until
light switches back to the equipment
outlet side. This point should
match the temperature reading
on the thermometer. If not,
turn knob back to the left,
adjust trim screw very slightly
and turn knob right again to
re-check switch point temperature.
When switch point temperature
matches that of thermometer
calibration is complete. During
adjustment, pressure on trim
screw will cause incidental
switching. This is normal and
has no affect on adjustment
procedure. |

| This example
shows the basic integrated functions
of the CT-DH-1. |
|
|
|
| |
|
| The CT-DH-2 is also designed
to turn "On" cooling and dehumidifying
equipment to remove excess heat
and humidity. However,
the CT-DH-2 offers you independent
outlets for heating or cooling.
The left outlets activate when
temperature exceeds your set
point. The right outlets activate
when humidity exceed your set
point. Set your desired
temperature and humidity using
the dials. Internal sensors
will allow a 7ºF temperature
comfort zone (3ºF with an external
coil or remote bulb) and
a 5% humidity span (differential)
between the time the fans activate
for cooling or dehumidifying
and then turn "Off" again. |
|
|
| The CT-DH-2 operates on 120
Volt AC with 15 Amp maximum
switching capacity and is intended
for indoor use only. Be
sure to locate your atmospheric
controller where it will accurately
sample and respond to the average
air conditions. Good air
circulation around the controller
and in your garden space is
essential. Avoid locating
the controller in a draft or
in direct sunlight. |
|
|
| This example shows the basic
independent function of the
CT-DH-2 for the purpose of operating
equipment intended to cool and
dehumidify. |
|
|
| The CT-DH-2 may be used to
operate fans or any other cooling
or de-humidifying equipment.
Use with the IR-1 to defeat
CO2 when exhaust fans are used
for cooling. The diagram above
shows how to install the CT-DH-2
to operate with CO2 enrichment.
When temperature increases above
the predetermined setting an
exhaust fan is used for cooling
purposes. Excess humidity is
resolved with a dehumidifier.
If a condition arises where
both temperature and humidity
are high, both the exhaust fan
and dehumidifier would run concurrently.
One side of the 24 Hour Dual
timer could control lighting
while the other side schedules
the day time cycle of the CST-1
which in turn controls CO2 generation. |

While the CT-DH-3 has many
applications, it was primarily
developed for use with CO2 equipment
and exhaust/ventilation fans.
The left side (or equipment)
outlets of the controller are
normally "ON" until defeated
when the right side outlets
are activated. Internal sensors
will allow for 7ºF temperature
zone and a 5% humidity differential
between the time that the fans
come "ON" and then turn "OFF"
again. When temperature or humidity
rises above your dial set points,
the right outlets will activate
and the left outlets will deactivate.The
right side outlets will remain
"ON" until the temperature drops
7º and/or the humidity drops
5% below your set points. At
which time, the right outlets
will shut "OFF" and reactivate
the left outlets.
OPTIONAL PHOTOSENSOR
The CT-DH-3 is also available
with a built in photosensor
(CT-DH-3P) to defeat the left
outlets during periods of darkness.
This optional feature is especially
useful when using the controller
in conjunction with CO2 enrichment
systems. |
|
|
| Exhaust or ventilation fans,
cooling or dehumidifying equipment
should be plugged into right
side outlets. CO2 enrichment
systems or other equipment you
want to defeat during exhaust
cycles, should be plugged into
left side outlets |
|
|
 |
| The CT-DH-3 operates on 120
Volt AC with 15 Amp maximum switching
capacity and is intended for indoor
use only. Be sure to locate
your atmospheric controller where
it will accurately sample and
respond to the average air conditions.
Good air circulation around the
controller and in your garden
space is essential. Avoid
locating the controller in a draft
or in direct sunlight. |
|
|
| The CT-DH-3P is installed for
cooling and dehumidifying control.
This unit may be used independently
or with many other Green Air Products
controls to create an integrated
system. When the temperature or
humidity raise above the predetermined
setting, the CT-DH-3P initiates
a venting cycle and CO2 generation
is momentarily halted. The Cyclestat
is used to time the frequency
and duration of the CO2 production.
In the event of an exhaust cycle
the Cyclestat will reset and immediately
replenish CO2 enrichment upon
completion of the exhaust function.
The CT-DH-3P has a built in photo
sensor that prevents CO2 operation
during darkness periods. |
| The CO2 generator or emitter
system are plugged into the Cyclestat
and the Cyclestat is plugged into
the left outlets of the CT-DH-3P.
The fan is plugged into the right
side. |
|
|
|
| |
|
| The CT-DH-4 and 4P
is designed to be used with
CO2 equipment, dehumidifiers,
and exhaust fans. While
it is similar to the CT-DH-3
it has the added feature of
independent outlets for temperature
and humidity control. It is
ideally suited for use with
dehumidifiers. Temperature above
your set point will activate
the right hand outlets and deactivate
the bottom left "CO2" outlet.
Humidity will activate the top
left "Dehumidify" outlet. Internal
sensors will allow a 7° temperature
comfort zone and a 5% humidity
(differential) between the time
the equipment comes "On" and
goes back "Off" again. Set the
temperature and humidity to
the desired settings. The CO2
outlet is normally in the "On"
position and is able to activate
CO2 equipment as needed. An
optional photosensor will defeat
CO2 enrichment during darkness
hours. Intended for indoor use
only. The CT-DH-4 operates on
120 Volts AC with 15 Amp max
switching capacity. |

|
 |
| The
CT-DH-4 is installed for cooling
and dehumidifying control. This
unit may be used independently
or with many other Green Air Products
controls to create an integrated
system. This diagram shows how
to install the CT-DH-4 for independent
control of exhaust fans for cooling
and a dehumidifier for removing
unwanted humidity while synchronizing
ventilation with CO2 enrichment.
When the temperature exceeds the
dial set points, the CT-DH-4 initiates
a venting cycle and CO2 generation
is temporarily defeated. The Cyclestat-4
is used to time the frequency
and duration of the CO2 production.
In the event of an exhaust cycle
the Cyclestat will reset and immediately
replenish CO2 enrichment upon
completion of the exhaust function.
The Cyclestat-4 timer has a built
in photo sensor that prevents
CO2 operation during darkness
periods. If you are using a CO2
timer that does not have a photosensor
you can get that option built
into as a CT-DH-4P. |
| The
CO2 generator or emitter system
is plugged into the Cyclestat
and the Cyclestat is plugged into
the bottom left CO2 outlet of
the CT-DH-4. The dehumidifier
is plugged into the top left "dehumidify"
outlet. The exhaust fans are plugged
into the right outlets. |
