ROOM PANEL

ROOMSTER II RTx

USER’S MANUAL FOR ASSEMBLY AND HANDLING

The room panel ROOMSTER was designed for cooperation with the

Expert PID Dynamic 4D regulators and chosen models of Luksus EKO PID
Dynamic regulators. It has a house temperature week program with the

exact measurement of the room temperature from 0,1oC. Thanks to the
built-in communication with the boiler the device displays information
about emergencies and measured temperatures. The panel has its’ own
memory for the user’s settings and in case of cooperation with the Expert
regulator it automatically synchronizes the actual timing from the boiler
controller, without having to adjust it manually.

I. Preparation for work.

The room panel ROOMSTER RTx connects wirelessly with the boiler
temperature regulator through radio communication module attached to
the regulator. The radio communication module and the room panel com­municate on the selected frequency channel. The default settings indicate
operation on the 0 channel. When in the room there are more than 1 room
panels operation, each of the module-panel pairs must communicate on
different frequency channel. In such case there is a necessity to change the
default settings.

1. Preparation of the communication module RTX.

When the boiler temperature regulator, either Expert or Luksus, is in
the built-in version, the communication module must be connected to the
regulator through putting the XLR plug to the appropriate socket in the
sensor panel on the boiler. In other cases the connection must be made
through connecting three-wire cable coming out of the module to the regu­lator terminal or valve intended for connect the panel:

If there is a necessity to change the channel, one must:

• Disconnect the module from the regulator ort urn the power off,

• Using a head screwdriver unscrew two screws placed in te back of the

module housing.

• Take the housing off.

• Using the code switch, set the channel number on which the wireless

connection with the ROOMSTER panel is going to be realized. .

• Screw the housing back on.

• Connect the module to the regulator – turn the power on.

2. Preparation of the room panel.

The room panel is powered from two AA batteries of 1,5V voltage. It
is advisable to use the alkaline batteries of good quality. In case of replacing
the batteries by NiCd rechargeable batteries of 1,2V voltage, the panel will
not work.

The panel is delivered to the client with no batteries included. In or­der to put in new batteries or change the discharged batteries one should
take the back site of the panel off using a small screwdriver and put the
batteries in accordance with the description attached to the housing.

Pushing the RESET button (available through round hole under the
tillable stand on the back part of the panel) or putting out and back in the
batteries will cause the program reset – the program’s version number will
be displayed on the screen for a moment.

If there is a necessity of changing the channel number on which the
panel communicates with the RTX module, one should:

• Cause the program reset

• During displaying the program version number, shortly push the

button,,

• A writing CH and the actual channel number will be displayed on the

screen,

• Using the buttons and set the new channel number,

• Confirm the changes by the button – one will be redirected to the

main screen

II. Main screen.

Normally, the main screen displays actual room temperature.

Additionally, the following elements might be displayed:

• - the active temperature program is marked by a rec-

tangle, OFF means that the program is turned off;

• designation of the active day temperature, designation of the

active night temperature; when the program is turned off, the screen
does not display any of these elements;

• wireless communication state; blinking element means no commu-

nication, after establishing communication the element lights con­stantly and it does not light at all in the low power consumption mode;

• days of the week from Monday to Sunday;

actual day is surrounded by a frame; elements are not displayed when
the temperature program is turned off;

• all active program

through all day; the black fields mean the active day temperature;

• active when the screen displays the actual temperature from the

weather sensor;

• active when the screen displays actual temperature of the boiler

shell;

• active when the screen displays actual temperature of the valve

sensor;

• active when the screen displays actual temperature of the hot do-

mestic water sensor;

• active when the room temperature is lower than the set tempera-

ture; means turned on reheating;

In order to enable the view or edition of the set values, one has the
following touch buttons:

• moving to the temperature programming screens

• moving to information screens

• increasing or decreasing the settings of the actually active

temperature or changing the set value during other parameters’ edition.

III. Rule of operation.

For regulation purposes the panel uses two temperature values of
the temperatures set by the user:

• Day temperature (comfortable temperature) – it is simultaneously

the set temperature for the room with the program turned on;

• Night temperature (lowered temperature).

Both names (day/night, comfortable/lowered) are contractual. For
example, the user might set the day/comfortable temperature at the level
of 15

o

C and the night/lowered temperature at the level of 25oC.

During the operation, regardless of the chosen work mode, one of
the temperatures mentioned above is always active.
