Typical Thermostat Home Screens
The images below illustrate the typical home screens on the thermostats. The screen is touch
sensitive and shows the current status of the thermostat. Inside the red/blue/white ring the thermostat
shows the current target temperature. The intensity of the red/blue ring changes based on the
temperature differing from the target temperature.
The colour of the blue red/blue ring can be set over the network. As default the ring’s intensity
changes based on the target value differing from the sensor 3 (built-in sensor) measurement.
The small action circle indicates the current measurements / network values in rotation.
Touchscreen
The room thermostat home screen has four touch sensitive areas that allow the thermostat settings to
be altered. All parameter values are available as Modbus/BACnet network variables.
• UP and DOWN arrows; to alter the current target (temperature / % value). 
• SMALL ACTION CIRCLE (that contains current main zone temperature etc.); allows access to
FURTHER SETTINGS AND INFORMATION screen. 
• FUNCTION BASED ICON; in PARTY mode shows the PARTY icon; in OFF mode shows the
OFF icon. Pressing the icon the mode can be cancelled. 
• FAN SPEED ICON; when FAN display is enabled, the fan ICON can be used to control the fan
speed (up to 7 steps, AUTO-0-1-2-3-4-5-6) 
• ECO ICON; when set the ECO mode icon is displayed below the fan speed 
• A/C ICON; when AC is enabled the AC can be enabled/disabled from this icon 
• LIGHTS ICON; when LIGHTS are enabled, the lights can be enabled/disabled from this icon 

Touchscreen Backlight
The touchscreen backlight level can be adjusted through the maintenance mode. During the normal
operation after 30 seconds of inactivity, the touchscreen dims to the “stand-by level set. If the backlight
level is set to 0, the screen backlight switches off.
By pressing the DIM icon when the screen is active the screen is immediately dimmed to the "stand-
by" level. Pressing the DIM icon when the device is in the "stand-by level", switches the backlight OFF.
The screen backlight is automatically activated when it is touched.
Measurement Displays
The SH-TSX thermostat can show up to 3 temperatures (sensor 1, sensor 2, sensor 3) in the ACTION
CIRCLE. With the RH humidity sensor option, the relative humidity sensor is also displayed in the
ACTION CIRCLE.
Sensor 1 can display the external sensor RI1 temperature, or temperature can be set
over the network (if Sensor1 Source has been set to network). The description for the
temperature can be changed via Sensor1 Text parameter in the configuration pages. By
setting the description to Disabled, the sensor reading is not displayed on the screen.
Sensor 2 can display the external sensor RI2 temperature, or temperature can be set
over the network (if Sensor2 Source has been set to network). The description for the
temperature can be changed via Sensor2 Text parameter in the configuration pages. By
setting the description to Disabled, the sensor reading is not displayed on the screen.
Sensor 3 can display the built-in sensor temperature, or temperature can be set over the
network (if Sensor3 Source has been set to network). The description for the
temperature can be changed via Sensor3 Text parameter in the configuration pages. By
setting the description to Disabled, the sensor reading is not displayed on the screen.
Note: If all sensor displays are Disabled, the ACTION CIRCLE displays the last drawn image.
Setpoint Mode
Inside the large circle on the HOME SCREEN the SH-TSX shows the target value. As default the units
are in temperature (Celcius / Fahrenheit). It is possible to change the units to ’percentage’ to display
the target values for percentage based control, or to show temperature only.
Setpoint Mode Options:
• TEMPERATURE: Setpoint is displayed in temperature (Celsius/Fahrenheit) 
• PERCENTAGE: Setpoint is displayed in percentage
• NONE: No setpoint is displayed. Instead of setpoint the Sensor 3 is displayed inside the circle.
If no other measurement is not displayed the ACTION CIRCLE change to the COG WHEEL
icon to indicate access to FURTHER SETTINGS screen.

• DISABLED (Default)
• FAN AND LINE BAR
• LINE BAR ONLY
• FAN ONLY
• FAN AND COLOUR
LINE BAR
• COLOUR LINE BAR
ONLY
When the fan level set to
more than OFF (Speed 0) via
network or manually (if
enabled), the fan icon
rotates. The current fan/level
is displayed by the shading
of the line bar (in 6
steps/bars).
The shading of the bar can
beset to follow greyscale, or
green/yellow/red colour
scheme. 
The system uses thelast command principle.If the fan speed hasbeen set/changed fromthe
network then thedisplay goes toautomatic mode(showing ’A’ next to theline bar if Auto option
selected). When thedevice is manuallyoverridden then the ’A’symbol changes to ’M’indicating
manualoperation (only if Autooption has beenselected for ManualControl). Otherwise thescreen
shows only the selected Fan Speed. 

External Sensor RI1 and RI2 Inputs
A remote NTC10k3 sensor can be connected to the RI1 and RI2 input and used for the monitoring
purposes. The measurement is always available over the communications network. If configured the
reading is also showed on the display in the SMALL ACTION CIRCLE area.
DI Digital Volt-Free Input
The digital volt-free contact can be used to override the interface to ECO and OFF/FROST
modes, or for just monitoring purposed. The configuration options are:-
• Close for ECO Mode
• Open for ECO Mode
• Close for OFF Mode
• Open for OFF Mode
• Alarm
• Network
• Close for Night
• Disabled
"Close For" Configuration - The digital volt-free contact can be linked to e.g. external timer to switch
the thermostat to OFF or ECO mode (input delay timer).
"Open For" Configuration - The digital volt-free input can be used to activate ECO or OFF mode when
the contact opens. In this mode it can be connected to a window switch or door card switch.
