Page 3: Quickguides
QUICKGUIDES QUICK INSTALLATION GUIDE We recommend the preparation of an area schedule chart on the backside of the user manual before commencing the installation. This identifies piping circuits to specific rooms and enables the correct allocation of a channel number in the WLM system. Mount the Master and AO modules in the correct way on the wall in accordance with electrical regulations. - Page 4 Connect the actuators to the channel outputs on the master in accordance with the pipe manifold layout (please refer to the area schedule). Actuator no. 1 on the manifold to output no. 1 on the master. Actuator no. 2 on the manifold to output no. 2 on the master. etc.

Page 6: Testing The System
TESTING THE SYSTEM: Switch on DIP-3 to activate learn mode: - power light will blink quickly Each red channel light on the master should now be lit if a Room sensor is present on that channel. Switch off DIP-3 to de-activate learn mode again – power light stops blinking. Turn all adjustable temperature settings on the Room sensors to minimum. -
Page 7: Troubleshooting
TROUBLESHOOTING: Problem Possible cause & solution Channel light is not coming on. Make sure the power light is fast blinking. If not then put DIP-3 to ON position. (When in Learn mode) 2-wire bus may be incorrectly connected. Voltage at each Room sensor should not be lower than 4.0V (check for + &... - Page 8 Output relay for Main pump, Cooling, High Incorrect connection to device (output relay has volt free contacts, see master wiring diagram for limit valve or other attached device. correct connection) Bad electrical connection between terminals and attached device. Install mode is not activated. Attached device may be faulty.
- Page 9 Room is too cold. The Room sensor is placed in a position that does not represent the general temperature in (After running for at least 48 hours) the room. E.g. mounted on external wall or near an extraneous heat source. If the room is controlled by a CT Room sensor, check that the time and temperatures are set correctly.

Page 15: Installation
INSTRUCTIONS Installation Fit the WLM master to a suitable wall. It will generally be found more convenient if the unit is within 0.8 metre of the manifold, as most thermal actuators are supplied with 1m cables. Cables can be run on the surface into the terminals using either the cable releases in the cover or by pressing out the cable entries in the lower part of the cover. -
Page 16: Pump Output
10 sec after the start of the main pump. Basic versions without display. Type WLM2-1BA and WLM2-3BA The boiler relay will stop if there is no heat demand measured by the Room sensors. -
Page 17: Thermal Actuators
The X relay output is volt free as shown in fig 8a. If the relay is required to be used as a L & N switch, connect a link wire from mains L to C1, connect the device L to C2, and the device N to mains N. Boiler pump: Where a boiler primary pump is required to be switched on from the master, the relay output can be used for this purpose. -
Page 18: External Switch For Night Setback
External Switch (TIMER) for night setback Fig 7 From factory the master is delivered with a jumper in the switch/ timer terminals I & O. The day temperature setpoint is defaulted to 20°C and the night temperature to 15°C. These default settings can be changed if the master has a display. -
Page 19: Room Sensors - Wireless Setup
Room sensors - Wireless setup: Fig 12 Where wireless Room sesors/controllers (WLTx-29) are being used is necessary for the WLM master to “learn” that the Room sensors/controllers are communicating correctly. To achieve this: 1. On master, switch on DIP-3 to activate learn mode: 2. -
Page 20: Setting Up Which Room Sensor/Controller Should Work With Wich Thermal Actuator
Setting up Which Room sensor Should Work With Which Thermal Actuator Each Room sensor can be selected to operate a specific output which in turn controls the thermal Fig 10 actuators on the manifold. Under the front cover of the Room sensor, a selector can be accessed, and the number of its output (its CH channel) can be set with a screwdriver. -
Page 21: Supply Water Temperature Sensor And Mixing Value
MANUAL, MASTER TYPE WLM2. Mixing valve actuator control Control of a mixing valve actuator is possible using the digital masters WLM2-1FS and WLM2-3FS The actuator must be 24Vac powered (max 6VA) and positioned via the 0-10V DC signal, and should be configured so that it closes the valve if there is no heating demand (0Vdc signal). The control signal can be reversed to 10-0V via the master menu system if required. -
Page 22: Creating A Network
INSTRUCTIONS Creating a Network In large buildings with more than 14 zones where multiple manifolds are utilized, it is possible to use multiple masters to create a single network. One master must be defined as the “network controlling master” by setting both encoders to zero (see pic). -
Page 23: Using Cooling Function
A hot water sensor is connected to the Room controller and measures the temperature in the storage cylinder. A zone valve is then controlled via the WLM2 master, which in turn activates the boiler on demand. • Install the hot water senser (ETF) on the hot water take off pipe immediately above the storage cylinder. -
Page 24: Radiator Control
• Connect the hot water sensor to the controllers sensor terminals. • Connect the hot water zone valve to an output on the WLM master and set the channel number on the hot water controller to the corresponding number. Note: When the WLCT/HW calls for heat it does not start the circulation pump on the under floor heating system Radiator control: It is possible to control a radiator circuit room temperature with a special Room controller (WLCT/R) to... -

Error Indication During normal operation the green power LED will be ON when the master control is energised. The red output Channel LED’s (1 to 8 on the master, and 9 to 14 on the add-on module) will indicate if the channel output relay is ON/OFF. An error / fault message is shown by flashing the green power LED or one of the 8 red output Channel LED’s. - Page 29 Flashing output LED (red): The appropriate output channel LED can flash, indicating that the room sensor or room contoller on that channel has a fault/error. The failure code can also be seen in the service menu (submenu 2a). E1, 1 flash The master has lost communication to the room sensor.
- Page 30 Each Room sensor with manual adjustment is capable of increasing or decreasing the preset DAY & NIGHT setpoints on the master by +/- 4C for the heating zone which it is controlling. The Room controller WLCT has its own DAY & NIGHT temperature settings that can be set separately, and if manual Room sensors are attached to its ”group”...
