The document presents collected information on safety, assembly and use of AURATON Taurus.
Wired control strip for underfloor heating
AURATON Taurus is an 8-zone, wired strip designed to work with wired temperature thermostats, actuators, a central heating pump, and a heating device.
| Q P |
WARNING! All connections should be made when power source is disconnected. AURATON Taurus is designed for mounting on a DIN-rail in the installation cabinets. |
Operation
AURATON Taurus works in the same way as 8 separate heating zone channels and additionally may perform the following functions:
- Control of a central heating circulation pump,
- Control of a central heating furnace via a transmitter with potential-free contacts.
- A diode indicating the status of the power supply
- A diode indicating the status of operation of the pump or the central heating furnace
- Terminals of wired thermostats 1-8
- Network switch
- Control of the central heating pump
- NC, COM, NO, potential-free contacts of the transmitter
- Terminals of heating zones 1-8 (actuators)
- Diodes indicating operation of zones 1-8
DIN rail mounting
- DIN rail.
- Hook the AURATON Taurus onto the DIN rail with the upper hooks.
- Pull the lower hook down with a “flat” screwdriver.
- Put AURATON Taurus in the right place.
- Release the lower hook.
For easy installation, the terminals are equipped with removable clamps. Before cable connections are made, they can be disconnected from AURATON Taurus.

WARNING: All connections should be made when power source is disconnected. One wired AURATON thermostat can be connected independently to each zone. |
Indication of operation of AURATON Taurus
AURATON Taurus indicates its operating status with LED diodes.
- A diode indicating the status of the power supply (red):
The power supply diode is off AURATON Taurus is off The power supply diode is on AURATON Taurus is in normal operation mode - Diode indicating the status of operation of the pump and the transmitter (green):
The diode is off No control of the central heating pump – the transmitter is off The diode is on The central heating pump is on – the transmitter is on - Diodes indicating operation of heating zones:
The diode is off The heating is off The diode is on The heating is on
Control of the central heating pump and the central heating furnace
The central heating pump and the furnace are turned on when heating is switched on in any of the heating zones – a diode that indicates operation of the central heating pump and the furnace will light up.
The central-heating pump and the furnace are switched off when none of the heating zones is active – the diode indicating operation of the centralheating pump will be turned off.
To improve the operation of the heating system, AURATON Taurus is equipped with a delay system for switching on the central heating pump and the furnace.
Such operation of AURATON Taurus is intended to manage the heating system reasonably and not to allow excessive load on the central heating pump, which could result in its premature wear.
When heating is turned on, first the actuators are switched on and then, about three minutes later, the central-heating pump and the relay are activated. The pump and relay switch-on delay time is indicated by the turned on LED of a given zone and by the turned off indicator light of the central heating pump. After that time, the pump and the relay are switched on and the indicator light of the central heating pump is switched on permanently.
The central heating pump and the relay are switched off when no heating zone is active.
Connection of the central heating furnace
The central heating furnace must be connected to the COM-NO or COM-NC clamps. This is a standard one-pole bistate transmitter. In most cases, the NC clamp is not used.

WARNING: All connections should be made when power source is disconnected. It is recommended to entrust the installation of AURATON Taurus to professionals. |
- Actuators
- Central heating pump
- Heating device e.g. gas boiler
Connecting multiple actuators to one thermostat
- Actuators (max 3 per 1 line)
- Central heating pump
- Heating device e.g. gas boiler
Connecting two AURATON Taurus devices
(common pump and furnace)
- Actuators
- Central heating pump
- Heating device e.g. gas boiler
The furnace and pump switch on times add up.
Cleaning and maintenance
- The outside of the device must be cleaned with a clean dry. Do not use solvents (such as benzene, thinners, or alcohol).
- Do not touch the device with wet hands. This can lead to electric shock or serious damage to the device.
- Do not expose the device to excessive impact of smoke or dust.
- Avoid contact of the device with liquids and moisture.
