How does it Work?
ModuSat® weather compensation works using an outdoor temperature sensor, which is connected to the Data logger (typically one for the whole project) and the information is constantly sent to the individual ModuSat® units via our SmartTalk® two-way communication system.
When the temperature changes outside, the ModuSat® controls adjust the set heating flow temperature according to the weather compensation slope, therefore the primary network temperature can be reduced respectively. This function enables for both: primary and secondary systems to be weather compensated simultaneously, as shown opposite. The weather compensation of the primary system is done by plant room controls or BMS.
This ensures a much quicker heating response time than conventional controls, where the increased demand for heating is noticed only when the room temperature drops. ModuSat® systems therefore ensure more comfortable environment by maintaining a constant room temperature, despite the changing weather.
The limit for primary weather compensation, minimum primary flow temperature (Min PF shown above) will be determined by the secondary flow temperature requirement for domestic hot water and heating.
Maximising the Heat Network Efficiency
Heat network efficiency will be greatly increased by allowing further reduction of network temperatures, therefore reducing the heat loss of the system, and increasing the efficiency of the main plant operation
Synchronised weather compensation for the primary and secondary system will lead to reduced system running costs and carbon emissions due to lowered heat losses.
