Automatic Curtain Adjustment
The next 3 settings allow an automatic increase in the on-time when the room
temperature is quite distant from the set point. There are times when the outdoor
temperature can change quite suddenly and a slow moving curtain can take a
long time to compensate for this sudden change. Then next 3 parameters can
greatly speed up the response of a curtain to a sudden and significant change in
temperature. Examine the parameters and the diagram and example on the
following page to understand how these parameters work. These settings will
affect the on and off times of both curtains in the same manner.
CCnA Curtain Timer Compensation No Adjust Band
The value entered here indicates the temperature range above and below the
Dead Band where the Curtain Open On-Time (Parameter OPn.1) and Curtain
Close On-Time (Parameter CLo.1), follow the On-Times set in Parameters OPn.1 and
CLo.1. This parameter is disabled if parameters CMOT and CCPb are set to 0.
CMOt Maximum On-Time
The value entered here indicates the Maximum On-Time that the curtain will use.
If the Maximum On-Time entered here is greater than the [Open On-Time
(Parameter OPn.1) +Off-Time (Parameter Off.1)], or greater than the [Close On-
Time (Parameter CLo.1) + Off-Time (Parameter O .1)], the controller will give the
Off-Time a value of 5 seconds. Otherwise, the on time is increased and the off
time is decreased as needed.
CCpb Timer Compensate Proportional Band
The value entered here indicates the bandwidth over which the curtain goes from
(Minimum On-Time, Maximum Off-Time) to (Maximum On-Time, Minimum Off
Time).
For example: Parameter SEt.1 (Set Point) 70.0°F
Parameter db.1 (Curtain Dead Band) 5.0°F
Parameter OPn.1 (Curtain Open On-Time) 60 sec.
Parameter O .1 (Curtain Off-Time) 60 sec.
Parameter CCnA (Cur. Timer Comp. No Adjust Band) 1.0°F
Parameter CMOt (Max. On-Time) 90 sec.
Parameter CCpb (Timer Comp. Prop. Band) 2.0°F
Using example settings: When the Temperature in the room increases and
reaches 72.5°F (Parameter Set.1 + 1/2 of Parameter db.1), the curtain starts to
cycle Open for 60 sec. (Parameter OPn.1) Off for 60 sec. (Parameter Off.1). The
curtain will continue to cycle Open 60 sec., Off 60 sec. for another 1.0°F increase
in temperature (73.5°F), since this is the value set in Parameter CCnA (No adjust
band setting). If the temperature continues to rise in the room (73.6°F to 75.5°F,
2.0°F bandwidth set in Parameter CCPb), the controller will gradually increase
the Open On-Time and decrease the Off Time until the Max. Open On-Time is 90
sec. (Parameter CMOt). The Off time would be reduced to 30 seconds. These
settings are only an example of how the controller is capable of lengthening the

If the direction button is
held for 8 seconds or more
the curtain movement will
'latch'. To indicate this, the
display will change from
horizontal lines
to horizontal lines
with sides
when latched.
Curtains will stay latched until the Mode button is pressed (or the opposite
direction is chosen). Note that latched curtain actuators will NOT operate
automatically. To return to display room temperature while latched, the Select
Arrows must be used to return to the default display Parameter. When a curtain
is latched, the Open or Close indicator will flash.
Wind Sensor Status:
If Wind Sensor Operation has been enabled (see the wind sensor settings in the
hidden settings) then this Parameter will indicate if the wind sensor is detecting
wind, if the curtain is closing due to wind and if the open delay timer is active.

Manually Move Individual Actuators
Press the Up Arrow to close the actuator for the zone. Press the Down Arrow to
open the actuator for the Zone. Individual actuators will latch if the direction
arrow is held for more than 8 seconds (See Above)
runt Run Time
This Parameter displays the number of minutes since the last
run time reset. This parameter is to be used in combination
with the next 2 parameters allowing the operator to determine
exactly how much the heaters are running. The maximum
value is 9999 minutes (just over an hour short of a full week).
When 9999 is reached all 3 timers stop counting.

Hidden Settings:
run Heat Control System On / Off
Whenever the heat mats or lamps are in-use, this setting must be set to “On”.
When set to Off, all output channels will be set to 0% output power.
DeGr Temperature Units
This parameter allows selection of temperature units between °F and °C.
Prb.1 Prb.2 Prb.3 Probes to use for Curtain 1, 2 and 3
This control supports up to 4 indoor probes. This parameter allows selection of
the probes to be averaged and used by Curtain zones 1, 2 or 3. Any
combination of the 4 probes can be selected. Setting this parameter to ‘off’ will
turn off the curtain and it will not move automatically.
Prb.4 Probes to use for Curtain 4
This parameter selects the probes to use for Curtain 4 similar to the above
setting. Note that Setting Prb.4 to ‘Off’ enables heat stages to operate using the
relays normally dedicated to operation of Curtain 4.
CLSt Wind Sensor Close Timer
This parameter defines how long the curtains will run closed after wind is
detected by the wind sensor. This is usually set to several seconds. The timer
gets reset every time wind is detected by the sensor. When this Parameter is set
to 0, the wind sensing function is disabled. If the control is not equipped with the
optional wind sensor board, this parameter must be set to 0 for proper operation
of the control.

7 sec.
Standard Settings:
Set.1 Set Point Zone 1
This parameter is the reference temperature for zone 1. The curtain will open
and close based on this temperature. The heater will also turn on and off relative
to this temperature.
If the security setting is on (Hidden Parameter SECU), it will not be possible to
adjust anything other than settings SEt.1 and SEt.2.
O S.1 Curtain 1 Temperature Offset
In certain cases, it may be necessary for one curtain actuator to work from a
slightly different reference temperature than the Set Point. The OFS.1 parameter
allows the user to specify a temperature offset. If the offset is set at 3.0°, then
the centre of the deadband will be found at the Set Point + 3.0°and the curtain
won’t begin opening till the room is warmer by 3.0°. If it is set at -3.0°then the
curtain will begin opening at a temperature 3.0°cooler than if this parameter was
left at 0.
db.1 Curtain Dead Band Zone 1
This parameter defines the dead band for Zone 1. This is the temperature about
the set point where the curtain will remain where it is. The dead band is centred
on the set point. A dead band of 3.6°will not move the curtain unless the
temperature climbs 1.8°above the set point or drops 1.8°below the set point.
OPn.1 Curtain Open On-Time Zone 1
When the temperature is high enough and the curtains are to open, the actuator
will open for the amount of time specified in this setting. Then the curtain will
stop and remain in place for the “Off Time” below. There are 3 settings in the
