3 Mounting and installation

Mounting

Installing your thermostat

●The thermostat is suitable for wall mounting.

●The recommended height is 1.50 m above the floor.

●Do not mount the thermostat in recesses, shelves, behind curtains or doors, or above or near heat sources.

●Avoid direct solar radiation and drafts.

●Seal the conduit box or the installation tube if any, as air currents can affect sensor readings.

●Adhere to allowed ambient conditions.

1.Switch off power to your heating system by using either your home’s breaker box or the system’s power switch.

2.Remove the cover of your old thermostat.

3.Label the wires according to your old thermostat terminal designations, using the stickers provided together with the thermostat. It is also helpful if you take a picture of the current wire connections for reference later on.

10 | 54

Siemens	A6V10877569_en--_a
Building Technologies	2017-09-08

Mounting and installation	3

4.Disconnect all the labeled wires and then remove your old thermostat. NOTICE! Do not throw your old thermostat in the trash if it contains mercury in a sealed tube. You can contact a thermostat recycling organization, for example, www.thermostat-recycle.org, for safe disposal of your old thermostat.

5.Check whether you need to have more wires connected to the power unit to be installed. If yes, prepare the wires and label them accordingly. Normally, at least three wires are needed for the thermostat to work meaningfully. It is strongly recommended that you turn to installers for wire connection.

6.Seal the conduit box or the installation tube to prevent entrance of cold or warm air and ensure the correctness of temperature readings by the internal sensor.

7.Screw the mounting plate tightly on the conduit box using a screwdriver, making sure that the mounting plate is placed correctly (the part with the upward arrow is placed on the top).

8.Connect the labeled wires to the terminal tightly according to your thermostat terminal designations (you may also refer to the picture you take in Step3), and then fix all the inserted wires by screwing down the screws. Note that the wiring for your application might be different from the schematic drawing shown below.

9. Screw the power unit on the mounting plate tightly.

10.Attach the front module horizontally, making sure that each side of the front module fully aligns with that of the power unit, and then press each corner of the front module until you hear a click sound.

3Mounting and installation


	11.	Switch on power to your heating system. Your thermostat powers on too.
Wiring	See the Mounting instructions for more information. Note that a bridge between
	one Q11 terminal and terminal L is pre-wired. It is not recommended to remove this
	pre-wiring bridge unless requested.
	●	Comply with local regulations to wire, fuse and earth the thermostat. It is
		recommended that the conduit box is connected to the earth (safety ground).
	●	Adapt the line diameters as per local regulations to the rated value of the
		installed overcurrent protection device.
	●	The line voltage cables and signal cables should be arranged separately.
	●	X1, M and X2 wires operate at SELV (Safety Extra Low Voltage) level. You
		must not insert cables of AC 230 V mains voltage into terminals X1, M and X2
		and vice versa.
	●	Isolate the cables of inputs X1, M and X2 from the AC 230 V mains voltage.
	●	The AC 230 V mains supply line must have an external circuit breaker with a
		rated current of no more than 10 A.
	●	You must not tear off the two insulation tapes on the lower part of the back of
		the power unit; otherwise, it might cause risks of electric shock.
	●	Properly size the cables to the thermostat and valve actuators.
	●	Do screw the cables tightly and ensure that no bare copper is exposed.
	●	Use valve actuators rated for AC 230 V. If a valve actuator rated for AC 24 V is
		used, use a transformer before connecting it to the thermostat.
	●	Disconnect from power supply before removing the front module and the
		mounting plate.

4Getting started with your thermostat

4.1Setup wizard

When your thermostat is powered up for the first time, a setup wizard displays to guide you through the following procedures:

●Setting a display language

●Setting an administrator password

●Setting up a network connection and choosing the network connection type

●Selecting an equipment type and setting up the details

●Configuring time and date

●Specifying a name to the location where the thermostat is installed

For more details, see the Quick guide.

Normal display

1Tap to display detailed information and additional settings.

2Displays whether the system is in an energy-optimized mode. If the leaf is red, predefined settings were changed. Tap the red leaf to restore the energy-saving mode. The leaf again turns green.

3Room temperature.

4Tap to toggle between At home and Away.

5Displays whether the thermostat is following a scheduler () or following your setpoint changes permanently (). Following a scheduler can mean the following:

●If there is network connection and you’ve also set your scheduler, the thermostat follows your scheduler. Your temporary change of the temperature setpoint only takes effect during the currently scheduled mode.

●If there is network connection but you haven’t set a scheduler, the

thermostat follows the default scheduler set by the system. For more information about the default scheduler, see Setting schedulers [ 45].

●If there is no network connection or valid time, the thermostat cannot retrieve scheduler information from the Cloud. It always works under the Comfort mode.

6Tap or slide to change the room temperature setpoint.

●If the icon is green, the air quality is good.

●If the icon is orange, the air quality is moderate.

●If the icon is red, the air quality is poor.

In order to ensure that the room air quality is measured accurately when the room is closed for a long time, it is recommended to force air circulation such as opening a window.

3Displays whether the system is in an energy-optimized mode. If the leaf is red, predefined settings were changed. Tap the red leaf to restore the energy-saving mode. The leaf again turns green.

4.3Home screen icon overview

Icon Description

The device is connected to the cloud but not associated with an account.

At home mode is on.

AWAY mode is on. You must manually tap to activate this mode.

Displays when the system works in an energy-optimized mode. If the leaf is red, it means that some pre-defined settings have been changed. You can tap the red leaf to restore to the energy-saving mode. The leaf turns green again.

Temperature setpoint slider. The background color of this icon changes along with major changes to the setpoints:

●If you increase the setpoint by dragging the slider to the right to warm up the room, the slider color changes to orange.

●If no heating occurs, the slider color changes to white.

Relative room humidity

The thermostat works following a scheduler. If you haven’t set one, the thermostat works following a default scheduler. This default scheduler could be set by the system, or specified by yourself if you have changed the default setpoints of some operating modes under Advanced settings > Optimization.

When this icon is toggled on, temperature setpoint changes can only be maintained within the current scheduled mode and will be overridden to the scheduled setpoint when the next scheduled mode starts.

NOTE: If the thermostat has never been connected to a WLAN network, it cannot read the real time from the network and thus cannot follow a scheduler. In this case, it always works under the Comfort mode.

The thermostat doesn’t work following a scheduler. All of your temporary setpoint changes work continuously if this icon is toggled on.

Tap to display options, such as Operation mode, Settings and

Advanced settings.

Presence detection	5
Presence detection using the built-in PIR sensor

5Presence detection

5.1Presence detection using the built-in PIR sensor

By using a built-in presence detection sensor (also called PIR (Passive infrared detector) sensor), the thermostat can detect the space occupancy and then do the following:

●Activate the idle display. When no operations are performed, the thermostat detects whether someone is in the room or not. If it detects someone is in the room, it displays information such as room temperature, room air quality and relative room humidity. If it detects no one is in the room, it turns off the screen.

●Change the operating mode from Economy to Comfort. If an unoccupied room is detected to be occupied when a scheduled Economy mode is running, the thermostat switches to Comfort automatically until the next scheduled mode starts. However, you can decide not to switch to Comfort if you want.

Sensor location

1The location of the PIR sensor. It is a black area if seen from the front of the front module.
