| Controls ventilation equipment to maintain desired temperature and humidity levels |
|
 |
| Connect your ventilation equipment, set the desired temperature and humidity levels; and if either one is exceeded the exhaust outlets (2) are activated |
|
 |
| Similiar to the AIR-1 with the addition of a photo cell and CO2 outlets. The photo cell insures that your CO2 device only works when the lights are on; and the AIR-3 will disable the CO2 outlet when the exhaust fans are on. |
|
 |
| The PPM-3 is the most afordable and simple CO2 controller available. Just plug your CO2 device into the unit and it will automatically maintain the CO2 level that you set. |
|
 |
| Easy to use - plug your fan into the control receptacle, then plug the control unit in 120v. power supply. Set the thermostat to a temperature you want the fan to cone on at and that's it! |

| The Cyclestat may be set for interval and cycle of timed events. Interval is the time between the "On" and "Off" cycles. The interval knob may be set from 5 minutes to 8 hours. Set this for desired time between functions. Cycle is the length of time that a specific function or condition must be maintained. Cycle may be set from 5 seconds to 30 minutes. |

| 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 7% 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 7% below your set points. At which time, the right outlets will shut “OFF” and reactivate the left outlets |
|
 |
| Will disable your lights if a set maximum temperature is exceeded, and will sense a power failure and delay starting for 15 minutes to avoid "hot starts" |
|
 |
| The HPR-1 is a hard-wired 30 amp capacity, 240 volt device for controlling multiple HID ballasts. A separate "trigger cable" is connected to your control device such as a time clock; when power is applied to the cable, relay then applies power to your equipment. |
