5.3.1 Manual Relay Operation
Any relay with a code of ‘0’ is not part of the automatic system. However, it follows the NO/NC (Normally
Open, Normally Closed) specification. To turn it on manually, (for an extended time, as for installing and
for troubleshooting) specify code 0, and set NO/NC to 1. To turn it off manually, set NO/NC to 0.
This method has the advantage that the
AC-2000
will not reset and return it to automatic operation, as it
does with test
Menu 33
. It permits the installer as much time as needed to check wiring and electrical
connections with the relay in a known position.
NOTE:
Return the relay code to the correct function so that AC-2000 can operate it properly.
5.3.2 Relay Record
A permanent record of relay assignments on a small card at the
AC-2000
provides important information
for servicing. By referring to the card, the service person can quickly test the correct output and identify
problems. Of course, written records of circuit breaker assignments, manual override switches, and other
connection information should also be available.
5.4 Sensor Layout (Menu 94)
The
AC-2000
supports up to six heating zones, each with individual heaters. The average of the zones
determines the overall house temperature for the ventilation system.
Menu 94
assigns particular sensors
to the heating zones for temperature, humidity, and static pressure. It also assigns outside sensors.
Temp Zone A: 1
Temp Zone B: 0
Temp Zone C: 3
Temp Zone D: 0
Temp Zone E: 0
Temp Zone F: 0
Radiation Zone A: 1
Radiation Zone B: 0
Radiation Zone C: 0
Outside Temp: 4
Humidity A: 0
Humidity B: 1
Outside Humidity: 0
Static Pressure: 4 (Internal)
CO2 Analog Input
NOTE:
For half or third house brood, set up the zones to prevent averaging in the grow end sensor. If
the cold grow end sensor averages with your heated zones, it causes the house temperature
to read too cold. This does not affect the heating, since the heaters use the individual zone
sensors. However, the ventilation may be incorrect and historical data may show incorrect
temperatures since the grow end sensor may have a much different temperature. ‘Extra’
systems (relay codes 31, 32 and 33), or positive pressure optimizer, if set to average
temperature, might work incorrectly.
