System Parameters details
•
==TEMP==
o
Offset: Use this parameter to change the offset target temperature up or down for any
purpose. Default: 0.0
o
Band: this refers to the target temperature zone range. The User’s Manual refers to this
as the Happy Zone. Default: 1.0
o
Cool Factor (%): the minimum correction towards target happy zone during each
increase ventilations delay (patience factor). If the temperature does not improve by this
amount, the controller will increase one level. Default: 10%
o
Cold Above TRG: Temp Change To Be Considered As Quick Drop In Degrees, To
Reduce A Level To Reach Above Target Temp (Degrees). Default: 3.0
o
Cold Below TRG: Temp Change To Be Considered As Quick Drop In Degrees, To
Reduce A Level To Reach Below Target Temp (Degrees). Default: 1.0
•
==HEATER==
o
Heat Band: Set the happy zone for the heaters on/off. Default: 1.0
o
Heat Lamp Diff: differential from target temperature to initiate heat lamps. Default: 0.0
o
Heat Offset: Use this parameter to change the offset Heat temperature up or down for
any purpose. Default: 0.0
•
==MIN MAX==
o
Curve: If Yes - Min max table curve between the days. Default: NO - Will work
according to previous line until current day.
o
Level Control: Four options for the min max table method: by days, soft minimum by
days, by time, soft minimum by time. Default: Day
o
Soft Min Temp: choice whether to use the current inside temperature or the outside
temperature to determine when to use the soft minimum. Default: OUT
o
Soft Temp Band: diff below heat temperature to set temperature at which to enforce low
temperature minimum ventilation level. Default: 10.0
•
==PRESSURE==
o
Press Control (Yes / No): If a pressure control should be done in Min Vent mode by the
inlet and in Tunnel mode by tunnel curtain, select Yes. Otherwise, select No. Default:
No.
•
==LEVELS==
o
Inc Delay Time: this is the standard minimum delay before increasing ventilation levels.
Default: 120 (sec)
o
Dec Delay Time: this is the standard minimum delay before decreasing ventilation levels.
Default: 180 (sec)
•
==TUNNEL==
o
1
st
Tunnel Level: switching into and out of tunnel ventilation is a major change in
ventilation. For tunnel ventilation, enter the first tunnel level here. If set on 0 there is no
tunnel level. Default: 0
o
Dif Below, Exit: this parameter sets amount below the tunnel entry temperature at which
to exit tunnel ventilation. Tunnel temperatures are determined by the sensors specified in
Temperature Definition. Entry and exit is also controlled by these sensors. The controller
cannot exit tunnel until the tunnel temperature is this much less than the tunnel entry
temperature. It must be a positive number. Default: 2.0
