02952 Well-Contact Plus Electronic Touchscreen Thermostat

Electronic touchscreen thermostat for ambient temperature control (heating and air-conditioning) of 2 independent zones, KNX standard home automation system, class I temperature control device (contribution 1%) in ON/OFF mode, class IV (contribution 2%) in PI mode, 1 NO relay output 4 A 24 V~, 1 input for wired temperature sensor or electronic temperature sensor, 1 programmable digital input, RGB LED backlighting, can be interfaced with actuator with KNX proportional analogue outputs to make a class V modulating room thermostat (contribution 3%), to be completed with Eakin, Ark or Plana cover plates – 2 modules.
The thermostat is suitable for controlling room temperature (heating/air- conditioning) in 2 or 4 pipe systems (heating/air-conditioning) and neutral zone (only in 4-pipe systems), with the “boost” function to activate a second source that enables reaching the desired thermal comfort faster; it can interact with other thermostats and with a supervision centre (PC with Well- contact Suite software). It can manage 2 temperature zones completely independently (equivalent to two thermostats A and B). For each zone the heating/air-conditioning modes are managed according to the relative reference temperature. It is equipped with a relay programmable as NC or NO that can be used for general use (e.g. lighting, closing zone solenoid valve, activating electric towel warmer, etc.) or to control speed 1 of the fan coil, which is managed by thermostat A or thermostat B. It also has a digital input programmable as NC or NO, which can be used for other applications such as detecting an open window. The thermostat features an RGB display with 5 capacitive buttons for controlling the temperature set-point and the speed of the fan coil, the configuration of the operating modes and the selection of thermostat A or B to view/control; it has an RGB backlit display whose colours can be adjusted via parameters with ETS.

CHARACTERISTICS.

Supply voltage: BUS 29 V SELV.
Consumption: 10 mA.
Terminals:
– TP bus;
– Digital input for NO or NC contact (with no potential, SELV);
– Maximum distance between the input contact and the thermostat: 30 m;
– NO relay output ( 24 V~ SELV 4 A cos 1; 24 V~ SELV 2 A cos 0.6).
Operating temperature: 0 °C – +40 °C (inside).
ERP classification (Reg. EU 811/2013):
– ON/OFF: class I, contribution 1%;
– PI: class IV, contribution 2%;
– with actuator with proportional analogue outputs KNX: class V, contribution 3%.
This device contains only SELV circuits that must be kept separate from circuits with dangerous voltage.
RGB backlit touch display with colours that can be configured via ETS parameter:
– fixed colour chosen by the installer;
– dynamic colour change depending on the set-point value by enabling the Eco meter function.
Internal temperature probe: measurement range from 0 to 40 °C with reading accuracy of:
≤±0.5 °C between 15 °C and 30 °C; ≤±0.8 °C at the extremes.
External temperature probe: measurement range from -20 to 70 °C with comparable accuracy to the internal temperature probe; beyond the stated temperatures, the error increases.
Temperature sensors that can be managed by the thermostat 02952 – Internal NTC.
– Possibility of connecting an external NTC art. 02965.1-20432-19432-14432.
– Possibility of using the temperature values sent over the bus from 8 different KNX temperature sensors ( DPT_Value_Temp data).
Reference temperature
For each of the two thermostats A and B the reference temperature for the climate control is the weighted average among all the available temperature sources (if present):
– Internal NTC;
– External NTC art. 02965.1-20432-19432-14432;
– via bus (KNX temperature sensors 1 to 8).
The weights of the various temperature sources are set via ETS; source temperatures with weight 0 are not included in the calculation of the reference temperature.
Systems management with:
– 2/4 pipes and on/off and proportional valves;
– Fan coils with 3 speeds, 3 proportional and constant proportional speeds;
– Neutral zone (only 4 pipes).
– Control algorithm: On/Off, I, PI.
Boost function: each thermostat A and B has a second temperature control stage which, if enabled, triggers to support the first one when the detected temperature differs from the desired set-point by at least a predetermined threshold”.
Ambient humidity display: the thermostat can display ambient humidity whose value is sent by the bus to the thermostat via appropriate data points.
Dew point
System protection functions:
– Antifreeze and Too Hot;
– Floor temperature protection;
– Generic alarm.
16 scenarios.

CONFIGURATION.

The configuration of the thermostat, physical address, parameters, its operation, etc., is done with the ETS software.
For all the details related to the ETS communication objects, the parameters and the configuration of the device, please refer to the Well-contact Plus manual you can download from the “Software -> Product software -> Well-contact Plus” section of the website www.vimar.com.
The user, by means of the front buttons, will be able to change the temperature set point and the speed of the fan-coil; changing these parameters forces the thermostat onto manual operation.

USING THE THERMOSTAT.

The thermostat lets you set:

the operating mode (Comfort, Standby, Economy, Protected, OFF) by tapping .
vary the speed of the fan coil by tapping .
increase the temperature set point in the room by tapping .
decrease the temperature set point in the room by tapping .
Depending on how you set the “Client Permissible Control” parameter, the set- point temperature can be changed freely or only within certain limits set by the control room or reception.
Thermostat B is selected by tapping .

INSTALLATION RULES.

Installation should be carried out by qualified personnel in compliance with the current regulations regarding the installation of electrical equipment in the country where the products are installed. The appliance must be installed in flush- or wall-mounting boxes with the relevant mounting frames and cover plates, at a height of 1.5 m off the floor, in a suitable position for correctly detecting the ambient temperature. It must not be installed in niches, behind doors and curtains or in areas affected by sources of heat or atmospheric factors. In particular, it must not be installed on outer walls or in association with appliances that generate heat (e.g. regulators or lamps).

IMPORTANT:

Max. length of cable connecting the external sensor: 60 m.
Use a twisted cable with a minimum cross-section of 0.8 mm² (art. 01890).
Maximum length of the cable for connecting the input: 30 m.
Make sure that the BUS line power supply unit has its earth terminal properly connected to the electrical system’s earth.
Note: In the phase of installation provide for cable connection lengths that allow extracting the device from the flush mounting box so as to be able to access the configuration button.

REGULATORY COMPLIANCE.
EMC directive.
Standards EN 50428, EN 50491.
REACH (EU) Regulation no. 1907/2006 – Art.33. The product may contain traces of lead.

WEEE – Information for users
If the crossed-out bin symbol appears on the equipment or packaging, this means the product must not be included with other general waste at the end of its working life. The user must take the worn product to a sorted waste center, or return it to the retailer when purchasing a new one. Products for disposal can be consigned free of charge (without any new purchase obligation) to retailers with a sales area of at least 400 m² , if they measure less than 25 cm. An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its subsequent recycling, helps avoid the potential negative effects on the environment and people’s health, and encourages the re-use and/or recycling of the construction materials.
