Sunlight Supply Grozone Control OSW On/Off 120V Switcher (Trigger Cord) - Manuel

OSW: ON/OFF 120V Switcher
Example use #1: Switch off CO2 enrichment when intake/exhaust
fans are running. O

Example use #2: Switch off the ventilation /exhaust/intake fans when
sulphur vaporizers are working.
Example use #3: Switch between two types of cooling equipment
(intake/exhaust fan versus water cooler or A/C).
Can turn on or shut off any piece of
equipment by means of a low-
current 120V sense cord.

Fan controller - example TP1 or TP2 - is given priority and activates fans
when temperature is too hot in the garden. When fans are activated, the multibar and OSW
sense cord are powered, causing OSW Off output (lower plug) to shut the burner (6) if already
on. In fact, the burner is activated by the CO2 Controller which supplies 120V to its output box
. CO2 injection is given lower priority and will be suspended when fans operate. CO2 injection
will only resume when fans are shut off, if CO2 ppm is still below setpoint.

Heating thermostat - example TP1 set to heating - is sensing outside air and
setpoint is set to 50°F. This thermostat supplies power to the OSW sense cord, in order to switch
between A/C or fan according to outside temperature. When outside air is cool (below 50°F in this
example), fan
is used instead of A/C , to save energy cost. When outside temperature is too warm
to cool down the garden (above 50°F), A/C is used instead of fan . A/C or fan are controlled
alternately by the same cooling thermostat - TP1 set to cooling.

24-H timer is given priority and activates vaporizers on programmed
schedule. When vaporizers are activated, the multibar and OSW sense cord are powered,
causing OSW Off output (lower plug) to shut the exhaust fan if already on. In fact, the
exhaust fan is activated by the Temperature Controller - example TP1 or TP2 - which supplies
120V to its output. Fan control is given lower priority and will be suspended when vaporizers
operate. Fan operation will only resume when vaporizers are off.
