Modern hotel installs the most modern room controller.
However, it is far more than aesthetics which is characterized by quality and thoughtful planning at the Clarion Hotel, Västerås.

The choice of technology to control the indoor climate and energy management has also been given high priority.

All rooms have controlled zones that give their users the opportunity to adjust the temperature.

The installed zone system takes care of the indoor climate.

Great potential for saving energy in parking garages
Automatic control of ventilation in parking garages saves a great deal of money while giving alarm for toxic gases.

Demand controlled ventilation for parking garages becomes economically advantageous in virtually all applications and generates in most cases an energy gain after a few months.

Detectors from AP warns of ammonia before concentration reaches health risk level.

The good part about ammonia leakage is that people notice small amounts by the unpleasant smell.

The NH₃ detector from the AP monitors ammonia in very small quantities.

The new ammonia detector measures down to 10 ppm and thus meets the requirements of the Work Environment Authority to give alarm at:

• Level value 25ppm (the concentration that a person may be exposed to during an 8 hour day without the fear of health hazards)

• Major alarm at max. level (maximum exposure time 5 min.) 50 ppm

Given these rules, two thresholds are monitored.

1. The first alarm alerts the technical staff and starts the ventilation system (if available).

2. Alarm for rising concentrations leads to the machine shut downs and the local emergency services are contacted.

The sensitive sensor can distinguish at low concentrations and respond rapidly. Response time is 35 seconds.

Detection range for this application is 0-100ppm. The application has a high accuracy of 4 ppm.

Operating temperature is -10° C ... +40° C and with internal heating elements down to minus 30° C.

Reliable measurement data for Energy Performance Contracting
A sun-ray protection, protecting outdoor-mounted temperature sensors from sporadic or direct solar radiation as well as the influence of heat from walls and ground, with a guarantee for reliable measurements of temperature control for energy efficiency in buildings.
 
WSS is a naturally ventilated sun-ray protection complete with accessories to provide a simple installation of humidity and temperature sensors.
 
Temperature sensors according to protection class IP65 are available with different measuring elements to be integrated in the control and automation system of the EPC.
 
For maximum protection, the screens' outer surfaces are white in order to reflect radiation. This gives very good outdoor measurement results.
 
The screen plates are made of a special material providing an excellent heat and UV stabilized function.

On Demand Controlled Lighting - Quick return of investment

In recent years, property owners, businesses, municipalities and other public institutions realize the benefits of planning their lighting.

In many offices, it is possible to reduce energy consumption from lighting by up to 70%, which means that the investment cost is very quickly earned and instead start saving money.

In addition to saving money, a review of the lights can also create a better working environment.

To achieve savings as huge as indicated above, a good lighting plan is needed with some sort of control system.

With a balanced control system connected to the light  detectors, which turns off lights when there is nobody in the room, we can save even more energy

These systems can also function at different levels, where you can gradually control the luminosity and then completely turn the light off. See the following links:

Efficient use of energy in the room with optimum indoor comfort

The MPC Combi Combi Controller links the building's technical functions such as lighting, heating/cooling, VAV, ventilation, emergency/monitoring, sunscreen, CO₂ and other features. As standard it is fitted with a open communication system designed to be connected to the BMS controller or the Web.

Settings are made with the keypad on the controller or the setup programme "MPC Manager" which is supplied free of charge.

Benefits of the MPC-Combi Controller:

• Simplified wiring

• Clear display that shows current temperature

• Reduces energy costs through tailored control, regulation of lighting, heating/cooling and ventilation.

• Universal I/O for analog and digital measurement and control signals as well as relay outputs.

• Local settings are made with the keypad on the controller for setting and adjusting the operating sequences, etc.

• Keypad and logotype can be adapted to different projects.

• The Intelligence is available in each MPC Combi controller and through amplifiers 247 units can be up to installed in a Modbus network.

The MPC is used in larger installations requiring high functionality, for example, offices, schools, churches, industry, flats, public places where building and integration between different property features are important, as well as in advanced facilities in villas as stand alone systems.

The MPC Combi controller can be delivered pre-programmed with desired function.
