INSTALLATION
CONFIGURATION
Terminating resistors may only be installed at the ends of the bus line.
No more than two line terminators are permitted in networks without repeaters.
The bias resistors for bus level definition in the idle state are usually activated at the
Modbus master / repeater.
The maximum number of subscribers per Modbus segment is 32 devices.
With a greater number of subscribers, the bus must be subdivided into several
segments separated by repeaters. The subscriber address can be set from 1 to 247.
A cable with a twisted-pair data line / power supply line and copper shielding braid must be
used for the bus line. The line capacitance should be less than 100 pF/m (e.g. Profibus cable).
The communication interface must be configured from the unit (see parameter table - System page 22).
All other parameters can also be changed via the Modbus master.
Changed communication parameters are activated when Setting Mode is exited; the unit performs a soft
reset. Alternatively, the new settings can also be activated by switching the unit off and on again (deacti-
vate and reactivate supply voltage).
The configuration parameters are stored in the non-volatile memory of the controller.
After changing the configuration via the display, the new parameters are saved when the controller
returns to Normal Display Mode.
If the changes were made via the bus (Modbus), the parameter for updating the non-volatile memory is
required in order to force saving. If configuration takes place via the display, the parameters are saved
after an expiry time or when the settings menu is closed.
An
existing configuration can be transferred to other units using the RYMASKON USB-CT
configuration tool (see next page).

RYMASKON®500 - BACnet
RYMASKON®500 - Modbus
The RYMASKON
®
500 Thermostat can show up to three temperatures and the
relative humidity (RH option) in the grey action circle.
Room, zone 1, main control circuit
The room temperature is used together with the target temperature in the
main
control circuit
to regulate the temperature. The internal temperature sensor is
connected by default. Alternatively, an external temperature sensor (NTC10K)
connected to RI1
⁄ RI2 can be used (Settings - Inputs - RI1 ⁄ RI2 Mode - Control).
The temperature value is always displayed and cannot be hidden. The name can be
changed (Settings - Display - Zone 1 Text).
Floor, zone 2, auxiliary control circuit, MIN - MAX
With the floor temperature, the temperature of a floor heating system can be
regulated via configurable temperature limits (min. limit/max. limit), for example.
The function and display is active if an external temperature sensor (NTC10K) is
connected to RI1
⁄ RI2 and the connected channel is configured to " MIN - MAX "
(Settings - Inputs - RI1
⁄ RI2 Mode - MIN-MAX).
The floor temperature is shown in the action circle. The name can be changed
(Settings - Display - Zone 2 Text ). If "Zone 2 Tex t " is configured to disabled,
the temperature is not displayed.
Outside, zone 3, simple display
The outside temperature is displayed in the action circle if an external temperature
sensor (NTC10K) is connected to RI1 ⁄ RI2 and the connected channel is configured to
"
Outside " (Settings - Inputs - RI1 ⁄ RI2 Mode - Outside). Alternatively, the unit can be
configured so that the outside temperature is transmitted via the bus to the unit
(Settings - Inputs - outside temperature source - network).
The
name can be changed (Settings - Display - Zone 3 Text).
If "Zone 3 Te xt " is configured to disabled, the temperature is not displayed.

MAIN CONTROL CIRCUIT
(Changeover)
Heating or cooling
The thermostat regulates the target temperature through the switching on and off of the relay, as required. In
this process, a hysteresis in the control program causes – in heating mode, for example – the target temperature
and the hysteresis to require being exceeded before the relay switches off. In cooling mode, the hysteresis
functions the other way around. This prevents switching on or off too quickly. The diagram below illustrates this
principle. The main temperature control circuit can be forcibly changed via the bus or through the digital input
(DI1) to heating or cooling mode (changeover). This makes it possible to use the same pipe for heating and cooling
in different seasons (summer/winter mode).
The target temperature can be adjusted by the user using the arrow keys UP and DOWN and it
changes depending on the operating conditions:
• In COMFORT MODE (standard mode), the target temperature (room)
can be adjusted by the
user or via the bus.
• In ECO MODE , the target temperature is switched over to t he ECO set point.
• In OFF MODE , the target temperature is switched over to t he frost protection s etpoint.

AUXILIARY CONTROL
CIRCUIT
(Floor, min-max)
Regulation of
floor heating /
floor cooling
If a temperature sensor is connected to RI1/2 and the input is configured to
auxiliary control circuit (Settings - Inputs - RI1/2 - Min-Max), the thermostat
monitors the floor temperature.
For
heating control i n Comfort/ECO/Boost mode:
• The relay is switched off when the upper limit of the floor
temperature is exceeded.
• The relay is switched on again if the floor temperature drops
by 1°C (hysteresis) below the upper limit.
• The relay is switched on when the lower limit of the floor tempera-
ture is undershot. This priority switching is overridden if the floor
temperature is once again 1°C above the lower limit (hysteresis).
The monitoring of the upper limit is typically used for protecting the floor
surface. The monitoring of the lower limit is primarily suited for bathers
to improve comfort when walking on the floor in bare feet or to dry damp
floor surfaces.
For cooling control in Comfort/ECO/Boost mode:
• The relay is switched off if the floor temperature drops
below the lower limit.
• The relay is switched on if the floor temperature is 1°C
above the lower limit (hysteresis).
The monitoring of the lower limit is usually used for preventing condensation.
Upper limit, lower limit and hysteresis are configurable.
(Settings - Control Settings - Min. Limit / Max. Limit / Limit Hysteresis)
The temperature limiting icon is displayed on the main screen to indicate
that the limit value control is active.

Configuration of "
Close for ": the voltage-free digital contact can be linked to an external timer,
for example, to switch the unit to ECO/OFF mode when the timer has elapsed. In the case of a
changeover from open (comfort mode) to closed (ECO/OFF mode), the operating mode only
changes once the time configured in the parameter "Digital Input Delay" has elapsed.
Configuration of "
Open for ": voltage-free digital input can be used to activate the ECO/OFF mode
when the contact opens. In this operating mode, it is suitable for the connection of a window
switch, door card switch or PIR sensor. During a transition from closed to open, the operating
mode only changes once the time configured in the parameter "Digital Input Delay" has elapsed.
Configuration of "
Changeover ": the digital input can be used for the priority switching of heating
and cooling mode. The unit works in heating mode when the contact is open and in cooling mode
when the contact is closed.
Configuration of " Alarm ": when the digital input closes, a "DI Contact Alarm" message is displayed
on the display.
Configuration of "
Bus ": the digital input is used for monitoring purposes via the bus.
No further effects on the regulation of the unit.
Units with an RH option can detect the relative humidity in the room with an accuracy of
2 % using an internal sensor.
The measured value is shown on the display in the small grey action circle.
The RH display is enabled by default and can be deactivated in the configuration settings.
The RH value can be accessed as a variable via the bus.

Depending on the system configuration, the unit can be switched
to
OFF mode via the display, the voltage-free digital input (e.g. with
an external timer) or the bus (under normal conditions, the relay
switches off).
OFF mode can be aborted by tapping on the OFF icon. The system is
designed so that the last command always determines the current
status. Example: if the unit has been set to OFF mode through priority
switching via the bus or via the digital input, the user can abort OFF
mode by tapping on the OFF icon. On the other hand, a networked unit
which the user has switched to OFF mode can be switched back to the
normal operating mode by the bus master.
If the unit changes to
OFF mode and then goes back into Comfort mode
(standard mode), the target temperature is reset to the nominal value.
The reset can be deactivated (Settings - Control Settings - Setpoint Reset).
NOTE: The availability of the OFF icon on the main screen
can be deactivated (Settings - Display - Show Off Icon).
FROST PROTECTION
In
OFF mode , the frost protection function is activated, and the set frost
protection target temperature is displayed (greyed-out). The frost
protection target temperature can be configured (Settings - Control
Settings- Frost Setpoint). If the room temperature in OFF mode drops
below the frost protection setpoint, the relay is switched on. The snow-
flake icon appears on the display . Once the temperature is 2°C above
the frost protection setpoint again, the relay is switched off.
The unit can be switched to ECO mode via the bus or the digital input.
ECO mode is also activated if Holiday mode is configured to ECO mode
(cf. section Holiday mode).
The ECO icon is shown on the display. Tapping the ECO icon in the main
screen to abort ECO Mode.
The last command applies, i.e. if was switched to ECO via the bus or
the digital input, the user can cancel the mode by tapping the ECO icon.

(1 zone).
The switching icon is enabled in the setting (Display - Lights/Blind).
NOTE:
Only
1 zone at a time can be switched for the light, air conditioning and blind functions.
A configuration for 2 light zones, 2 air conditioning zones or 2 blind zones is not possible.
The light ,
climate and blind functions share two icon positions on the main screen. All possible configurations are
displayed in Fig. 9a - 9e.
Tapping the icon so that the unit displays the blind screen .
Depending on the configuration in the settings menu, an adjustment of the blind can be made on the blind
screen using the arrows with different increments and movement types. The step size and movement types
can be configured as follows (Settings - Display).
Blind mode (increments):
• 2 positions (On/Off)
• 5 positions (4 increments)
• 11 positions (10 increments)
• Infinite/1% increments
The positions are distributed equally from 0–100%.
Blind configuration (movement type, graphical illustration):
• translatory movement "Level" (Fig.10a)
• rotary movement "Tilt" (Fig. 10b)
• translatory + rotary movement "Level + Tilt" (Fig. 10c)
Briefly tapping one of the arrows on the
blind screen to change the displayed value (0–100%) by the
configured increment. Use the bus to retrieve and change the value (blind position).
If
infinite increment is set, the control responds to display actions as follows:
• Briefly tapping the arrow to change the value by 1%.
• tapping an arrow for longer than 0.6s to change the value automatically; then let go of the arrow.
Automatic change stops by briefly tapping the arrow or when the minimum / maximum value
(0% / 100%) is reached.
The valid command is always the latest one. That means that if the blind position has been changed
via the bus, the user can change the mode value again, and vice versa.
