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 Text" 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 Text" is configured to disabled, the temperature is not displayed.

AUXILIARY CONTROL CIRCUIT
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 the ECO setpoint.
• In OFF MODE, the target temperature is switched over to the frost protection setpoint.
