ECtemp 550 1.2 Safety Instructions Make sure the mains supply to the thermostat is turned off before installation. If the thermostat is installed in a network, the mains supply to all thermostats in the network must be off. IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35°C.
ECtemp 550 2 Mounting Instructions Please observe the following placement guidelines: Place the thermostat at a suitable height on the wall (typically 80-170cm.). The thermostat should not be placed in wet rooms. Place it in an adjacent room. Always place the thermostat according to local regulation on IP classes. Do not place the thermostat on the inner side of an exterior wall. Always install the thermostat at least 50 cm. from windows and doors.
ECtemp 550 Do not place the thermostat in a way that it will be exposed to direct sunlight. Note: A floor sensor enables a more accurate temperature control and is recommended in all floor heating applications and mandatory under wooden floors to reduce the risk of over-heating the floor. ▪ Place the floor sensor in a conduit in an appropriate place where it is not exposed to sunlight or draft from door openings. ▪ Equally distant and >2cm from two heating cables.
ECtemp 550 Follow the steps below to mount the thermostat: 1. Open the thermostat: Push down the release tab. Carefully detach the front cover. Remove the two screws. Carefully detach the display module. Make sure to pull it straight out to avoid damaging the 8-pin connector plug on the back of the module. ▪ Carefully detach the frame.
ECtemp 550 2. Connect the thermostat according to the connection diagram. IP30 0T30 D550 Max.Load Mains 16 (1) A 220-240V~ L N LOAD LOAD N L devinet Sensor NTC The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector. The devinet terminals are used when connecting thermostats in a network.
ECtemp 550 3. Mount and reassemble the thermostat. = Screw holes for mount and reassemble the thermostat. ▪ Fasten the thermostat to a socket or an exterior wall box by driving the screws through the holes in each side of the thermostat. ▪ Install the frame, display module, and front cover in the reverse order of disassembly. Make sure to carefully put the display module in place and do not over-tighten the screws. 4. Turn on the power supply.
ECtemp 550 3 Settings The thermostat is automatically activated when the power supply is turned on. Note: If the unit has never been activated before, basic configuration settings must be specified. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 12 Symbol for frost protection. Numeric display of time, temperature, text, etc. Day of week. Flashing indication of actual time. Symbol for setting of time and day. Symbol for timer mode. Symbol indicating that the floor is being heated.
ECtemp 550 3.1 Time and Day of Week Settings 1. Press and hold the button for 3 seconds. The clock symbol appears on the display and the day of the week is shown as a number (from 1-7) just below the time. You change the day of week by turning the button in either direction and the time passes 00:00. 2. Find and set the correct day and time. A black dot will appear on the outer ring at the same time. 3. Press the button once to confirm.
ECtemp 550 3.2 Basic Settings The following table shows the default values of the basic settings: Item Default setting Options Network type Alone (ALO) Independent (ALO) Master (MAS) Slave (SLA) Adaptive function On (AdAP) On (AdAP) Off (OFF) Sensor Room + floor sensor (rFS) Floor sensor (FS) Room sensor (r S) Room + floor sensor (rFS) Max. floor temperature +35 °C +20 to +50 °C Offset 0.0 °C -5.5 to +5.
ECtemp 550 How to enter the basic configuration settings 1. Press and hold the button for 12 seconds until “COdE” appears. 2. Turn the button clockwise until “0044” appears. 3. Press the button once to confirm. Network: How to specify whether you want to connect this thermostat with other thermostats in a network Please note that the slave units must be connected to the master unit using the devinet terminals. 1. Define the thermostat as independent, master or slave unit.
ECtemp 550 To define this unit as a slave unit in the network, choose SLA. Only one unit in the network can be defined as master unit. All slave units will respond to and send information to the master unit. Time, day of week and economy periods will be controlled from the master unit. All other settings must be specified for each slave unit. No more than 32 units can be combined in a network including independent units (even though these units do not communicate with the master unit). 2.
ECtemp 550 Adaptive regulation: How to specify whether or not to optimise this thermostat for the room by timing heating start/stop 1. Turn the adaptive function on or off. To let the unit continuously collect updated room data, choose AdAP. This means improved performance (with compensation for e.g. sudden temperature drops in the room) and precise timing so the selected temperature is achieved at the desired time.
ECtemp 550 Sensor: How to specify whether an external floor sensor, the built-in room sensor or both is used to control the floor heating 1. Turn the button to choose one of the following sensor settings: If both a room sensor and a floor sensor is used, choose rFS. This option is suitable for all rooms but wet rooms. The thermostat must be installed in the same room as the floor sensor and the heating elements. If only a floor sensor is used, choose FS. The built-in room sensor is not used.
ECtemp 550 How to set the maximum floor temperature Special condition: This setting only applies if a floor sensor is used (the FS or rFS sensor option has been set). 1. Turn the button to change the temperature. 2. Press the button once to confirm your selection. Note: Please contact the floor supplier before changing the maximum floor temperature and be aware of the following: ▪ The floor temperature is measured where the sensor is placed.

ECtemp 550 Temperature decrease: How to specify how much the temperature is to be lowered during economy periods Note: If normal room heating is installed, we recommend lowering the temperature by no more than approx 5 °C. By default, the temperature decrease is set to -5 °C 1. Turn the button to set the setback level. For example, choose -4 °C to lower the temperature by 4 degrees. 2. Press the button once to confirm your selection. The display returns to normal.
