sygonix 2353939 Digital Programmable Room Thermostat Operating Instructions

sygonix 2353939 Digital Programmable Room Thermostat

Intended use

The heating thermostat is intended for temperature control in conjunction with an electric heater. To operate the product, it must be connected directly to the mains voltage. A consumer also operated via the mains power supply can then be connected to the product and switched on or off by regulating the temperature. It is equipped with an internal and external sensor (probe). The external sensor can be used to measure the temperature at a different location to the thermostat, such as on the floor with an electric floor heating system. Button lock can be activated to protect against incorrect operation and the product is equipped with memory storage to preserve data in case of power failure. The product has protection class IP20 and is suitable for dry rooms and indoor use only. Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be avoided under all circumstances. For safety and approval purposes, do not rebuild and/or modify this product. If you use the product for purposes other than those described above, the product may be damaged. In addition, improper use can result in short circuits, fires, electric shocks or other hazards. Read the instructions carefully and store them in a safe place. Always provide these operating instructions when passing the product on to a third party. This product complies with the statutory national and European requirements.

Installation/connection

The product should only be installed by people with relevant electrical knowledge and experience! *) If it is not installed properly, you risk:

• your own life
• the life of user of the electrical device
• If it is not installed properly, you risk severe damage to property, e.g. by fire. You face the risk of personal liability for personal injury and material damage.
• Always consult an electrician!

Technical knowledge required to perform the installation:

• The following specialist knowledge is required for installation in particular:
• The ‘Five safety rules’: Disconnect from the mains; secure against reactivation; ensure dead; earth and short-circuit; cover or protect adjacent live parts
• Use of suitable tools, measuring devices and personal protective equipment, where necessary
• Analysis of measurement results
• Use of electrical installation materials to meet the requirements for disconnection
• IP protection classes
• Installation of electrical installation materials
• Type of power supply (TN system, IT system, TT system) and the corresponding connection criteria (classic earthing, protective earthing, requisite additional measures etc.)
• If you are not a professional, do not do it yourself, always have it carried out by a specialist.

Further warnings:

• The design of the product corresponds to protection class II (double or reinforced isolation). Ensure that the insulation of the housing is neither damaged nor destroyed.
• During installation, all poles must be disconnected from the mains voltage, e.g. via a RCD. There must be an appropriately dimensioned fuse or circuit breaker between the RCD and the product.
• The device must be dead during installation and connection. Furthermore, turn off the automatic circuit breaker and the RCD to disconnect all poles from the mains voltage. Secure it against unauthorized reconnection, e.g. with a warning sign. Check to make sure there is no voltage with a suitable measuring instrument (e.g. a digital multimeter).
• Never connect the product to the power supply immediately after it has been transferred from a cold environment into a warm environment (e.g. during transport). The condensation that forms might destroy the device. Moreover, there is risk of electric shock!
• Allow the product to reach room temperature. Wait until the condensation has evaporated. In some cases, this may take several hours. Only once the condensation has evaporated should it be installed, connected to the power supply and put into use.

Protection class

• The product or its housing has protection class IP20 and is suitable for operation in dry rooms and indoor use only.
• There is no protection against water, combustible gases or vapours.

Code	Descriptions	Settings	Default value
A1	Temperature calibration	Setting range: -9 to +9 °C	-1 °C
A2	Switching differential (hysteresis)	Setting range: 0.5 to 2.5 °C Example: For a setting of 1 °C and the thermostat temperature set to 20 °C, the thermostat will switch heating on at 19 °C and off at 21 °C.	1 °C
A3	High temperature protection/difference setting (external sensor)	Setting range: 1 to 9 °C Example: The limit value ‘A6’ is set to +45 °C and ‘A3’ to 2 °C. If a temperature of +45 °C is reached, heating mode is interrupted. If the temperature drops to +43 °C, heating mode is resumed. This only works if the indoor temperature is lower than the target temperature.	2 °C
A4	Sensor selection	N1 = The internal sensor controls the temperature. N2 = The external sensor controls the temperature. N3 = The internal sensor controls the temperature. If N3 is activated, the external sensor is used as the temperature limiting sensor. With all of the settings above, if the maximum temperature is reached, heating mode is interrupted.	N1
A5	Button lock	0 = All buttons except on/off are locked 1 = All buttons are locked	0
A6	High temperature protection	If the temperature measured by the sensor rises above the value set here, heating mode is stopped automatically (e.g. serves as overheating protection for underfloor heating). Setting range: +20 to +70 °C To deactivate this function, press and hold the down arrow button (12) until ‘–’ appears on the display.	+45 °C
A7	Low temperature protection	If the temperature measured by the sensor drops below the value set here, heating mode is activated automatically (e.g. serves as frost protection). Setting range: +1 to +10 °C To deactivate this function, press and hold the up arrow button (11) until ‘–’ appears on the display.	+5 °C
A8	Minimum temperature	Sets the lowest selectable temperature value. Setting range: +1 to +10 °C	5°C
A9	Maximum temperature	Sets the highest selectable temperature value. Setting range: +20 to +70 °C	+35 °C
AA	Descaling	0 = closed 1 = open	0

Code	Descriptions	Settings	Default value
AB	Behaviour after power failure	0 = Return to previous function 1 = Switch off 2 = Switch on	0
AC	Weekly cycle setting	0 = 5 days identical + 2 days identical (Mo – Fr + Sa – Su) 1 = 6 days identical + 1 day individual (Mo – Sa + Su) 2 = 7 days identical (Mo – Su) The correct day of the week must be set for the program to recognise the start of the weekend. For further information, see “c) Setting the date and time”.	0
AD	Restore all settings to factory defaults.	Press and hold the time button (8) for three to five seconds until all elements on the display light up at the same time. All system settings are reset to the factory defaults.

Error codes
If the internal or external sensor is faulty, the display shows a corresponding error code and the thermostat switches heating on until the fault is rectified

Code	Descriptions	Suggestion
E1	Internal sensor error	Switch the thermostat off and contact technical support service or other technical personnel.
E2	External sensor error	Check the external sensor connection. Switch the thermostat off and contact technical support service or other technical personnel.
