following:
- VDE ⁄ VDI technical temperature measurements, directives, measurement set-ups for
temperature measurements.
- EMC directives
- It is imperative to avoid parallel routing of current-carrying lines
- We recommend the use of shielded cables with the shielding attached to the DDC/PLC at one side.
Before mounting, make sure that the existing technical parameters of the measuring instrument comply
with the actual conditions at the place of utilization, particularly with regard to:
- the measuring range
- the maximum permissible temperature and humidity

- oscillation, vibration and impacts must be avoided (< 0.5 g)
Devices with integrated CO2-Sensor
Devices with integrated CO2-Sensor have an automatic calibration of the carbon dioxide measurement –
ABC logic.
The Automatic Background Logic is a self-calibrating mechanism that is suitable for use in
applications in which the CO2 concentration regularly drops to fresh air level (350 - 500 ppm).
This should typically happen at times during which the rooms are unoccupied.
The sensor reaches its normal accuracy after 24 hours of continuous operation in an environment which
has been exposed to a fresh air supply of 400 ppm CO2. The deviation error remains minimal with at least
4 cases of sensor exposure to fresh air within 21 days. The ABC logic requires continuous operating
cycles of longer than 24 hours in order to function properly.

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 42).
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
(deactivate 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).

The RYMASKON
®
500 / 600 / 700 series of room control units are designed for controlling the climatic
zone in residential, hotel and office rooms and individually regulate the heating/cooling steps of the internal
rooms. A colour touch display with modern icons is used for the visual display and operation at the location.
The product range is characterised by the variety of combination options of the individual components.
The
RYMASKON
®
600 Controller series regulates through analogue outputs (0–10 V) up to two heating
or cooling valves
(6-way valves can also be controlled) and the fan (EC ventilator).
The
sun protection (blinds, shutters) can be controlled in two zones via the bus. Through the appropriate
symbols, it is possible to control the
light instead of the sun protection.
In addition to the integrated temperature sensor, two external temperature sensors (NTC10K) or two
analogue sensors (0–10V) can also be connected. Measuring elements for relative humidity and CO2 are
also available. The devices are used in room climate technology, including convector fans, cooling ceilings
and heating/cooling systems. Wall mounting is performed on standard in-wall flush boxes. The devices are
optionally available with a Modbus or BACnet communication interface and in various type versions (see

The small
action circle (grey) alternately displays the current sensor values (if enabled).
The large setpoint ring illustrates the heating or cooling consumption (red/blue).
If temperature control is in the “dead zone”, the ring is white.
The colour intensity changes depending on the difference between the actual temperature and
the currently controlled heating/cooling temperature (setpoint). From a delta of 2°C (3.6°F) or more,
the entire ring is red/blue.

TEMPERATURE
CONTROL CIRCUIT
Temperature Control
Loop Operation
The controllers can control up to two heating and cooling stages. The default is one heating and one cooling stage.
Furthermore, use the digital input, the measured temperature or the bus to automatically switch between heating
and cooling mode (Changeover). This allows various control configurations:
• 1-/2-step heating control
• 1-/2-step cooling control
• 1-/2-step heating control and 1-/2-step cooling control (up to 3 outputs)
• 1-/2-step heating/cooling control (with automatic switching – Changeover)
The controller modulates the required output capacity for heating and cooling depending on the calculated target
and actual temperature using P or PI control. The calculated target temperature consists of the nominal target
temperature plus the adjustment made by the user.
In the preferences of the RYMASKON
®
610 / 620 / 630 controllers , the output capacity
for heating stage 1 is linked to analogue output Y2 (0–10VDC control) and the output capacity
for cooling stage 1 is linked to analogue output Y3 (0–10VDC control).
RYMASKON
®
640 / 660 controllers have
their heating stage 1 linked to digital output DO1 (PWM control) and
their cooling stage 1 linked to digital output DO2 (PWM control).
The control circuits can be configured to directly or inversely control the outputs.
In inverted mode, the output and/or the valve is regulated from 100 % to 0 %.
This can be set separately for each stage in the configuration parameters.
There is a “dead zone” (
HDz + CDz ) between heating stage 1 and cooling stage 1. P control in the “dead zone”
results in a heating and cooling consumption of 0 %. PI control in the “dead zone” regulates the heating and
cooling consumption to 0 % if the actual temperature is in that range for a longer period of time. The “dead zone”
tolerates variations in the target temperature range without opening the heating or cooling valves. The controller
has an integrated lock preventing simultaneous heating and cooling consumption.
Use
HDz (Heating Deadzone) and CDz (Cooling Deadzone) to asymmetrically set the “dead zone” left and right of
the calculated setpoint
calcSP . In some cases it may be important for the cooling process to respond more quickly
than the heating process if the actual temperature deviates from the setpoint.
NOTE: Conceptually, calcSP – HDz is the effective target temperature for heating and calcSP + CDz the effective
target temperature for cooling. It is easier for the user to configure and calculate a single setpoint. The
dead zone limits are configured during commissioning to specify effective heating and cooling setpoints.
Users can adjust the target temperature using the arrow keys UP and DOWN.
The target temperature/dead zone changes as follows depending on the operating modes:
• Comfort mode (standard mode): The target temperature is adjusted by the users or specified via the bus and
shown on display. The calculated target temperature (calcSP) consists of the nominal target temperature and
the setting adjusted by the user on the display. The dead zone is adjusted according to the parameters to
“Heating DZ COMFORT” (HDz) and “Cooling DZ COMFORT” (CDz). The possible adjustment range is limited by
the parameter “SP Adj. Max” and “SP Adj. Min.” (default ±3°C).
• ECO mode: The nominal target temperature remains unchanged. Adjustments made by users are
disabled and the dead zone is adjusted to “Heating DZ ECO” (eHDz) and “Cooling DZ ECO” (eCDz)
according to the parameters.
•
OFF mode: The control ensures that the configured antifreeze-setpoint is met (fSP).
Adjustments made by users are disabled.
NOTE: If limit value control is enabled, the set upper and lower limits move the effective and/or calculated target
temperature as required (see chapter “Limit value control”).

LIMIT VALUE
CONTROL
High/Low Limit Control
The main temperature control circuit of heating and cooling stages 1 can be
forcibly switched to heating or cooling mode via the bus (Changeover).
This makes it possible to use the same pipe for heating and cooling in different
seasons (summer / winter mode).
Configure and perform the switching to the following values:
• Digital input (Digital Input Mode)
• Temperature measurement RI1 / RI2 (RI1/RI2 Mode)
• Bus (Changeover function)
If RI1/RI2 is selected, the system switches automatically
at the set temperature limits “Changeover High” (default: 25 °C)
and “Changeover Low” (default: 20 °C)
NOTE: If the unit has analogue inputs AI1 / AI2 instead of RI1 / RI2 ,
Changeover is only possible via the digital input or the bus.
If an external temperature sensor is connected (to RI1 or RI2) and
if the input is parameterised to “Floor (NTC10K)” (see chapter “Modes for
inputs RI1 and RI2”), the controller can be used for limit value control via
High Limit Setpoint (default: 35 °C) and Low Limit Setpoint (default: 16 °C).
This function is enabled via the parameter “Limit Ratio”
(default: 0.0 = limit value control disabled).
For controls with the
upper limit value (High Limit Setpoint), the target
temperature of the main control is reduced by the set value of the limit
ratio if the temperature on RI1/2 exceeds the upper limit value. Example:
If the value 2 is set for limit ratio, the target temperature is reduced by
2 degrees for every degree over the high limit setpoint.
Control using the
lower limit value works vice versa:
For every degree that the temperature undercuts the lower setpoint,
the target temperature is increased by 2 degrees.
The value for the
target temperature reset follows this formula:
setpoint reset = (limit setpoint - actual temperature RI1/2) × limit ratio
NOTE: The target temperature shown on the display does not change
during these increases/decreases. The temperature limiting
icon points to an active reset phase.
NOTE: The limit value control is enabled using the parameter “Limit Ratio”
(default: 0.0 = disabled).
NOTE: In OFF mode, limit value control is disabled.

CO2
CONTROL CIRCUIT
CO2 Sensor Control
Loop Operation
(Units with CO2 option)
Units with CO2 sensor can measure and monitor the CO2 content in the room air to control relevant applica-
tions on that basis and, e.g., increase the fresh air supply if the CO2 concentration is high. To lower the CO2
concentration, the control circuit can be linked to any of the physical outputs (
Y1, Y2, Y3 ) or the fan (fan speed
source). As an alternative, use the CO2 control circuit for maximum consumption control
“ Max. VAV ” or “ Max.
Fan
” (configurable in the parameters Y1, Y2, Y3 and fan speed source).
The CO2 control circuit corresponds to the CO2 setpoint and the CO2 proportional band. If configured for direct
control (typical) and the CO2 content exceeds the setpoint (limit value), the control circuit will start to modulate
the output capacity to 100 %. If the CO2 content in the proportional band range is above the setpoint, output
capacity is 100 %. Use the parameter settings to configure the control circuit. It can also be configured for
proportional and integral control (PI) by changing the integral reset time from 0 to a required higher value. Use
the parameter “CO2 Dir.” to change the direction of the actuator (direct, inverse).
In
OFF mode , the output capacity of the CO2 control circuit is set to 0 %.
In ECO mode , the CO2 control circuit works the same way as in standard mode.
Use the configuration parameters to enable/disable the display of the CO2 sensor.
VAV maximum consumption (Max. Temp / CO2)
Each analogue output can be configured for “ Max. VAV ” (maximum volume flow).
In that case, the relevant output ( Y1, Y2, Y3 ) takes on the maximum consumption capacity
of the CO2 and of the cooling temperature control circuit. Typically, this is used with
consumption-controlled ventilation to open ventilation flaps when more fresh air is needed
or to supply the room with fresh cooling air to lower the temperature.
Maximum blower consumption (Max. Temp / Hum)
Each analogue output can be configured for “ Max. Fan ”.
In that case, the relevant output ( Y1, Y2, Y3 ) takes on the maximum consumption capacity of the
CO2 and of the blower control circuit. If the CO2 content is high and if the blower control circuit
consumption increases, this is a way to maximise the fan speed.

Loop Operation
(Units with RH option)
Units with RH option can measure and monitor the relative humidity in the room to control relevant applications on

For humidification and de-humidification, the control circuit can be linked to any of the physical outputs
( Y1, Y2, Y3 )
or the fan (fan speed source).
As an alternative, use the humidity control circuit together with the temperature control circuit to control the fan
speed (
Max. Temp / Hum , see chapter “Fan control”).
The direction of both outputs can be inverted to regulate the actuators from 100 to 0 % instead of from 0 to 100 %.

The controllers have an auxiliary control circuit for a second zone . This control circuit provides an
additional PI control function for applications needing an additional control circuit.
Use the AUX parameters in the settings or the bus to configure this additional control circuit.
To enable it, set “RI1 Mode“ or “RI2 Mode “ parameter to AUX control circuit.
To control the temperature in the second zone, assign the AUX control circuit to an analogue
output (
Y1, Y2, Y3 ). Use the bus (not the display) to control the auxiliary control circuit.
NOTE: RI2 is not available with Type 620 .
The controller has a boost icon (if released),
and it can be linked to priority switching for a configurable boost time.
The
boost time (timer) can be configured from 0 to 480 minutes
(0 = permanently enabled, switch off boost using the display or the bus).
