Exhaust Outlet
This outlet receives power when excess heat or humidity need to be ventilated. Intake and exhaust fans or other venting equipment can be automatically functioned according to the set-points on the thermostat and humidistat dial face. There is approximately five points differential between "On" and "Off" cycles to maintain a consistent air quality.
CDDS-1 Trigger
When using a CO2 monitor to determine and control CO2 producing equipment this outlet provides 24 hr. power which is defeated during exhaust functions to minimize CO2 loss. Plug CDMC-2 digital sequencer into this trigger to integrate CO2 management with atmospheric control.
Timed Outlets
These outlets are operated by the 24 hr. time clock. Use to function almost any electrical equipment according to time of day settings. This precision synchronous clock provides 96 independent 15 min. On - Off trippers. Use the HAR-1 relay for high amperage or voltage equipment.
HR-1 Relay
This feature provides power for heaters or heating relays. A small heater with built in thermostat can be plugged directly into HR-1 outlet. Larger units must use heating relay HR-1 to isolate high amperage requirements. Set heating thermostat to minimum allowable temperature and cooling thermostat to maximum high temperature. The span between these two settings is the comfort zone. The HR-1 relay outlet will not operate during exhaust functions.
Cycle Outlet
The cycle outlet utilizes the same internal short cycle timer and operates simultaneously with the CO2 outlet. When the photo sensor mode switch is in the cycle timer position the timer is not interrupted by the photo and exhaust defeat circuits. Both outlets will provide 24 hr. sequence timing for irrigation systems, pumps, solenoids, transformers, motors, relays and many other equipment devices.
CO2 Outlet
Carbon dioxide enrichment equipment can be precisely timed through this outlet by the on board cycle timer. This timer will repeat your pre-set "ON" and "Off" periods continuously whenever the photo sensor detects the presence of light. The duration of the "On" cycles are from 5 sec. to 30 min. and the frequency of "On" cycles ( or the "Off" time between them ) is from 7 min. to 8 hrs. The photo sensor mode switch must be in the CO2 timer position for photo and exhaust function defeat circuits. Reset feature will replenish CO2 immediately after exhaust cycle. Switch mode toggle to "Off" for manual reset.
HF-1 Relay
This outlet is similar in function to the HR-1 relay outlet except it is for humidity producing apparatus. Humidifying equipment can not function during dehumidifying cycles.
Important: Make certain the combined amperage draw of all equipment operating through the MCC-1 does not exceed 15 amps. Use function relays to conduct high amperage or alternate voltage currents.
