Getting started
Thank-you for purchasing a Phason PLUS control. This manual will help you get the most out of your
PLUS control. Read the manual before installing and configuring your PLUS control.
See Installing the PLUS control on page 15 for installation and wiring instructions. The equipment
connected to the PLUS control must not draw more current than what the control stages are rated.
Equipment that is rated higher than the control ratings will damage the control and void the warranty.
Fill out the Variable speed settings,Relay stage settings, and Inlet actuator settings worksheets.
Use these set-up sheets when making changes to the control’s set points.
If you plan to use the growth curve, fill out the Growth curve setup sheet, and then program the
growth curve settings before adjusting the individual stages.

The Status bar Phason
2 2005-04-13
The Status bar
The Status Bar shows the present status of all stages of the PLUS Control.
NOTE The PEC+ layout is shown. The SEC-HD+ has only three relay stages and one actuator
stage.
•The Alarm indicator lights up when an alarm condition exists.
•The variable speed indicators, VS-1 and VS-2, light up when power is being supplied to variable
speed fans 1 and 2. You may notice one of these indicator lights glowing fainter than the other, the
fan represented by the fainter light, is running at less than full speed.
•The stage indicators, ST-1 to ST-6 (ST-1 to ST-3 for the SEC-HD+), indicate which relays are ON
or OFF.
•The TEMP indicator lights up when the digital display is showing a temperature.
•The TIME indicator lights up when the display is showing a time setting. Two digits to the right of
the decimal will be shown when the value is less than 10.0 minutes and only one when the value is
10.0 minutes or greater.
•The SPEED indicator lights up when the display is showing a speed value (0 to 100%).
•The POS indicator lights up when the display is showing a position value (0 to 100%).
•Pressing Max/Min displays the maximum ambient temperature in the room or zone over the
previous 24 hours, press it again to display the minimum ambient temperature over the previous 24
hours.
•The display “blinks” in this mode. This lets you know the displayed temperature is not the current
temperature. If you press the button again, it will restore the current ambient temperature. If you
forget, the control will display the current ambient temperature in a few seconds.

PLUS user manual Making adjustments to the system

Making adjustments to the system
The OK button saves changes. The display shows Acc (accepted) when you press OK. If the display
shows PIN, you must enter your PIN (personal identification number) before the settings will be
accepted. The control will NOT save the changes until you press OK.
The Mode button allows you to scroll through the programming modes. A green indicator lights up in
the active panel (STAGE MODE, VSP MODE, ACT MODE, or G.C.MODE.)
The Up button allows you to increase the value on the display. Holding the button will cause the
settings to change at a faster rate
The Down button allows you to decrease the value on the display. Holding the button will cause the
settings to change at a faster rate.

Stage mode Phason

Stage mode
Use the Relay stage settings worksheet on page 28 to help configure your PLUS control.
NOTE The PEC+ layout is shown. The SEC-HD+ has only three relay stages. You must press OK
after each change to save the settings.
The STAGE MODE indicator at the bottom right of the panel glows green when
you are in stage mode.
On the PEC+, the Stage 1 to 4 indicators light up if two inlet actuators are
connected to the control. If only Stage 1 and 2 are illuminated, only one inlet
actuator is connected. If no indicators are lit up in the left column, no inlet
actuators are connected.
On the SEC-HD+, the Stage 1and 2 indicators light up if an inlet actuator is
connected to the control. If no indicators are lit up, no inlet actuators are
connected.
The SEL button scrolls through the stages and the Alarm Hi/Lo. The indicators
in the left column light up when you select the corresponding stage. If you scroll
past your desired stage, keep scrolling through the stages by pressing SEL until
you reach it.
Heat or cool
You must designate a relay stage as either heat or cool. To do this, press the
H/C button. The HEAT indicator lights up when you assign the stage as ‘heat’.
The COOL indicator lights up when you assign the stage as ‘cool’. You cannot
assign a relay as a ‘heat’ or ‘cool’ stage if it has been assigned to an actuator.
Duty cycle
You can designate a relay stage as a duty cycle relay stage (after designating it as either heat or cool)
by using the O/C Time (relay open/relay closed time) button to set an ON and OFF duration for the
relay. The most common uses for this are misters and curtain machines.
The ON time is the duration a relay is active. The ON indicator lights up when this mode is selected.
The OFF time is the duration a relay is inactive. The OFF indicator lights up when this mode is
selected. The duration is set in hundredths of a minute. See the example below.
Toggle to ON to set the ON time for the relay. The digital display will show the current setting, use the
Up or Down buttons to adjust the duration the relay will be closed (active).
Toggle to OFF to set the OFF time for the relay. The digital display will show the current setting, use
the Up or Down buttons to adjust the duration the relay will be open (inactive).
Example: If you set the ON time to 100 and the OFF time to 500, the relay will be active for one
minute, then inactive for five minutes. When the temperature rises above the set point for a cooling
stage (falls below for a heating stage), the relay will be active for one minute, then inactive for five
minutes. After the five minutes, the control does a check; if the temperature is still above the set point,
the relay will be active again for one minute, then inactive for five minutes.

PLUS user manual Variable speed mode
170057 rev 13 5
Variable speed mode
Use the Variable stage settings worksheet on page 28 to help configure your PLUS control.
The VSP MODE indicator at the bottom right corner of the panel glows green when you are in variable
speed mode.
Press VSP Sel to select the variable stage. The VSP-1 or VSP-2
indicator lights up beside the active stage.
Each time you press VSP Fn, a different function is selected. The
indicator light glows red beside the active function. If you miss the
function you want to adjust, or need to make changes to a
function, press the VSP Fn button to scroll through the functions
until the desired function is active.
Repeat the steps below for each variable stage.
Range
Range is the temperature at which the fan hits full speed (maximum ventilation). When the Range
indicator is lit, you can adjust the Range by pressing Up or Down. The Range cannot be below the
temperature set point (Temp SP). Press OK to save the setting, and then press VSP Fn to move to the
next function.
Temp SP
Temp SP is the desired or ‘target’ temperature for the room or zone. It is also the point at which the fan
will start to increase from minimum idle to full speed. When the Temp SP indicator is lit, you can adjust
the Temp SP by pressing Up or Down. This setting cannot be above the Range or below the idle off
setting. Press OK to save the setting, and then press VSP Fn to move to the next function.
Minimum idle
Minimum idle is the speed the fan will operate at when the temperature is between the Idle off and
Temp SP settings. It is a percentage of full speed. When the Min idle indicator is lit, you can adjust the
Minimum idle speed by pressing Up or Down. Press OK to save the setting, and then press VSP Fn to
move to the next function.
Idle off
Idle off is the temperature at which the fan turns off. When the Idle off indicator is lit, you can adjust the
Idle off temperature by pressing Up or Down. This setting cannot be above the Temp SP. Press OK to
save the setting, and then press VSP Fn to move to the next function.
NOTE You must press OK after each change to save the settings.
