Description Type WLT
Thermostats type WLT are electronic thermostats suitable for hydronic heating in residential and light commercial applications. The thermostats are designed to control the indoor comfort temperature, with a high level of accuracy. The wide product program covers all typical applications, with choices of tamperproof, or partial or full adjustability, all working on a low voltage safe electrical system. The thermostats are suitable for surface mounting as well as flush mounting and are easy to install. For the European market they can be mounted in combination with various types of light switches, forming a semi flush mounted assembly.

2-Wired System
The thermostats are wired with a standard installation cable in any combination, in the conventional star format, or in series (as a daisy chain), using 2 core cable, from 0,25 mm2 up to 1,5 mm2 size to the master WLM (Water Line Master).
14 thermostats can be connected on the same system, each being able to control one or more thermal actuator.
The length of the cables can be up to 300 m in total, with max. 100 m between two points.
The 2-wire system is a low voltage system and ensures communication between the thermostat and the master.
An additional thermostat can be added to an existing WL installation and connected to the nearest or any convenient adjacent WL thermostat.

Easy to Install, Easy to Use
WL thermostats require no special tools for installation, standard cable is used, and the voltage is less than 5V on the bus. The well constructed user-interface makes operation easy.

Modularity = Flexibility
Choose a standard system, or upgrade with additional features to meet your unique needs. Extending an existing WL system is simple.

Optimal Comfort
A remote floor sensor can be used to limit the temperature in wooden floors, or to ensure that a warm and comfortable floor can exist in bathrooms all the year round. An optional 4 event clock thermostat allows you to define different temperatures in single or groups of rooms at different times to ensure maximum comfort.

Intelligent Design
From the 4-event clock feature to the unit's silent operation, WL thermostats are a smart investment. What is more, they look great in any residential or light commercial application.

Zone Control
With the use of the WLCT clock thermostat, a zone of one or more rooms can be made. The clock thermostat has a 4-event program allowing different room temperatures at different times. All non clock thermostats selected as belonging to that zone will work according to the temperature settings and times as programmed in the clock thermostat. However, a further adjustment of +/- 4°C can be made by the user on any non clock thermostat allocated to the zone. This allows fine tuning of the temperature in any single room.

For example, two zones could be set up :

  • Zone 1 could be the sleeping area, with three rooms.
  • Zone 2 could be the living room and kitchen, with perhaps three rooms. If each of the two zones has a clock thermostat, then they can operate independently of each other. T

the setting of which non clock thermostats should belong to which zone is done by simple programming in the clock thermostat.

Clock Thermostat
The WLCT thermostat is a thermostat with built-in timer specially developed to provide economical heating comfort.
The thermostat is simple to operate and the inclined display with icons makes it easy to read the information displayed.
The clock thermostat is delivered with a factory-set program for automatic comfort and setback mode. At installation you only need to set time and day.

The thermostat Can be Set to 3 Different Modes:

Clock Mode
The timer function is activated (normal setting) and the thermostat controls the heating system automatically in accordance with the 4-event program.

Manual Mode
The timing function is suspended and the required temperature can be set using the UP/DOWN keys, for example to 5°C, for frost protection when going on holiday.

Comfort Mode
The required temperature can be set for a single event using the UP/DOWN keys. At the next event, the thermostat will automatically return to clock mode.
The selected mode will be valid for all the thermostats belonging to the defined zone.
