Mounting Instructions
CAUTION: Remove power to avoid a risk of malfunction.
A. Remove the captive screw that’s holding the base and the front cover of the unit together.
B. Lift the front cover of the unit to separate it from the base.
C. Pull all wires through the holes in the base.
D. Secure the base to the wall using wall anchors and screws (supplied). Make the appropriate connections.
E. Mount the control module on the base and secure using the screw.
Do not use the supplied screws to mount the unit to an electric box or an equivalent device. The supplied screws are only suitable for
mounting the unit to the wall. Ensure to use the appropriate screws for any other application. Tighten by hand only and ensure not
to overtighten the screws.
Programming Mode
The Mode Selector jumper JP1 must be set to the PGM position (Programming Mode). Refer to the Wiring section on page 1. To exit,
set the jumper back to the RUN position (Operation Mode). Advance to the next or return to the previous setting in order to save a
changed value.

Setpoint & User Control
1. “Intern Temp Sensor Offset”
Range: 0 to 50ºC (32 to 122ºF)
Offset: Max. ±5ºC (±9ºF)
Increment: 0.1ºC (0.2ºF)
Compare the displayed temperature reading with a known value from a thermometer or other temperature sensing device. To offset or cali-
brate the sensor, use the arrow buttons to set the desired temperature reading. This is useful for controllers installed in areas where the tem-
perature read is slightly different than the room’s actual temperature. For example, a controller placed right under the air diffuser.
2. “User Setpnt Minimum”
Default: 15ºC (59ºF)
Range: 10 to 40ºC (50 to 104ºF)
Increment: 0.5ºC (1.0ºF)
In Operation mode, you cannot decrease the setpoint to less than the value set as the minimum user point. The minimum value is restricted by
the maximum value set at Step 3, “User Setpnt Maximum”. In other words, the value that is set as the minimum cannot be greater than the
maximum value.
3. “User Setpnt Maximum”
Default: 30ºC (86ºF)
Range: 10 to 40ºC (50 to 104ºF)
Increment: 0.5ºC (1.0ºF)
In Operation mode, you cannot increase the setpoint to more than the value set as the maximum user point. The maximum value is restricted
by the minimum value set at Step 2, “User Setpnt Minimum”. In other words, the value that is set as the maximum cannot be less than the
minimum value.
4. “User Setpnt locked”
Default: No (Unlocked)
Range: No (Unlocked), yES (Locked)
If set to No, the user setpoint option is not locked and the user can adjust the desired temperature setpoint. If set to yES, the user setpoint
option is locked and the user cannot set the desired temperature setpoint. A lock symbol appears to indicate that the setpoint is locked.
5. “User Setpnt”
Default: 22ºC (72ºF)
Range: 10 to 40ºC (50 to 104ºF)
Increment: 0.5ºC (1.0ºF)
Set the desired temperature setpoint within the defined range. If the setpoint option was locked at Step 4, “User Setpnt locked”, a lock symbol
is displayed. The setpoint value is restricted by the minimum at Step 2, “User Setpnt Minimum” and maximum at Step 3, “User Setpnt Maxi-
mum” values. In other words, the setpoint should be within the minimum and maximum setpoint range.
6. “Temp Control Mode”
Default: Auto (Automatic)
Range: Auto (Automatic), HEAt (Heating Only), COOL (Cooling Only), On (Cooling or Heating), CLHt (Automatic only)
Select the control mode that you want to authorize to the user. To authorize all the available modes, select Auto (Automatic Mode). The cooling
and heating symbols are also displayed. The selection made at this step determines the options available via the Control Mode (see page 33).
7. “Enable On Off Control Mode”
Default: yES (Enable)
Range: yES (Enable), No (Disable)
If set to yES, the user can set the unit to “Off” via the Control Mode (see page 33). If set to No, the “Off” selection does not appear in the Con-
trol Mode.
8. "Display Info"
Default: t - Hu %RH °C (temperature, humidity, and cooling heating demand)
Range: t - Hu %RH °C (temperature, humidity), StP %RH °C (temperature, humidity setpoint), OFF (no display),
t - Hu %RH °C (temperature, humidity, and cooling heating demand), StP %RH °C (temperature, humidity setpoint, and cooling
heating demand)
Select the desired information to appear on the display.

• t10v. If selected, the controller uses a 0 to 10 Vdc external temperature sensor. If you select t10v, Step 109, "UI1 Minimum Voltage",
124, "Extern Temp Minimum", 125, "Extern Temp Maximum", 126, "Extern Temp Sensor Offset" will be available.
• CO2. If selected, the controller uses a 0 to 10 Vdc CO2 sensor. If you select CO2, Step 128, "CO2 Maximum Range" will be available.
• OCC. If selected, the controller activates the occupancy status.
• nSb. If selected, the controller activates the night set back status.
• oVrd. If selected, the controller activates an alarm to indicate that there has been an override and the controller is forced into OFF
mode.
• win. If selected, the controller activates an alarm to indicate that the window is open. If you select win, Steps 146, "Window Open
Mode" and 147, "Window Fan Mode" will be available.
• door. If selected, the controller activates an alarm to indicate that the door is open. If you select door, Steps 148, "Door Open Mode"
and 149, "Door Fan Mode" will be available.
• dFt. If selected, the controller activates an alarm to indicate that the filter is dirty.
• FLS. If selected, the controller activates an alarm to indicate that the airflow is absent. The controller shuts off all outputs.
• oVht. If selected, the controller activates an alarm to indicate that the heating equipment has overheated. The controller shuts off the
heating outputs.
• SEL. If selected, the controller activates the Local mode. The controller shuts off fan outputs.
• FrFb. If selected, the controller senses the pulse feedback of the ECM motor.
• HU. If selected, the controller activates the humidity mode.
• P10V (Pressure 0-10V). If selected, the controller uses a 0 to 10Vdc pressure static sensor. If you select P10V, Step 109, "UI1 Mini-
mum Voltage" and Step 133, "Pressur Maximum Range" will be available.
• t012 (Extern Temp TT012). If selected, the controller uses a 10kΩ type 24 external temperature sensor. If you select t012, Step 126,
"Extern Temp Sensor Offset" will be available.
• dt1t (Delta Temp Inlet 10K). If selected, the controller uses a 10K type 3 temperature sensor. The controller selects this temperature as
the inlet temperature in the ΔT control mode.
• dt1u (Delta Temp Inlet 0-10V). If selected, the controller uses a 0 to 10 Vdc temperature sensor. The controller selects this temperature
as the inlet temperature in the ΔT control mode.
• dt0t (Delta Temp Outlet 10K). If selected, the controller uses a 10K type 3 temperature sensor. The controller selects this temperature
as the outlet temperature in the ΔT control mode.
• dt0u (Delta Temp Outlet 0-10V). If selected, the controller uses a 0 to 10 Vdc temperature sensor. The controller selects this tempera-
ture in the ΔT control mode.
If you select one of the following options: OFF, t10.0, SENs, noCL, noHt, OAS, t10V, CO2, HU, P10V, or t012, Steps 110 and 111 will not be
available.

Smart Communication Room Controllers User Manual
Issue Number 7.0
11/05/2022
Universal Input 1 (UI1) (continued)
109. "UI1 Minimum Voltage"
Default: 2.0
Range: 0.0, 2.0
This option appears only if you have selected either P10V or t10V at Step 108, "UI1 Signal Type". Select the minimum voltage for AI1.
110. "UI1 Contact"
Default: NO (Normally Open)
Range: NO (Normally Open), NC (Normally Close)
This option appears only if you have selected any one of the options: OCC, nSb, oVrd, win, door, dFt, FLS, oVht, SEL at Step 108, "UI1
Signal Type". Select the desired contact option.
111. "UI1 Delay Seconds"
Default: 120 seconds
Range: 0 to 3600 seconds
Increment: 10 seconds
This option appears if you have selected any one of the options: oVrd, win, door, dFt, FLS, oVht, SEL at Step 108, "UI1 Signal Type". Set the
delay in seconds before the state of input for UI1 is changed.
Universal Input 2 (UI2)
112. “UI2 Signal Type"
Default: OFF
Range: OFF, t10.0, SENs, noCL, noHt, OAS, t10V, CO2, OCC, nSb, oVrd, win, door, dFt, FLS, oVht, SEL, FrFb, HU,
P10V, t012, dt1t, dt1u, dt0t, dt0u
Select the input signal type for UI2 (Universal Input 2). Same options as Step 108, "UI1 Signal Type".
