Smart Energy Regulation & Control

How does our Smart Energy Regulation & Control work?

ModuSat® HIU’s feature smart energy regulation and control, which includes advanced Proportional Integral Derivative (PID) control logic, in combination with Pressure Independent Control Vales (PICV’s) and a fast-acting actuator. This provides a myriad of benefits in terms of HIU performance, optimisation for heat network efficiency and ongoing customer support –

• Pressure Independent Control Valves (PICV’s) provide integrated differential pressure control, providing balanced, self-configuring flow through the HIU
• Fast acting, electronically regulated actuators provide immediate response to changes in energy demand
• Proportional Integral Derivative (PID) control logic provides accurate actuator/valve control and fast response to hot water demand, without “overshoot” (Reduces energy wastage)
• Electronically actuated PICV’s also function as a shut off valve, so ModuSat® Smart HIU’s can easily be configured for either credit or PAYG billing systems

In addition, ModuSat® HIU’s are supplied prepayment ready with a room controller meaning there is no requirement for additional controls, sensors or equipment to provide remote monitoring of temperatures and flow rates or to switch the end user to a debt free PAYG system.

Smart Energy Regulation & Control enables the ModuSat® Smart HIU to deliver energy efficiency features such as –

• Fully programmable hot water “Keep-warm” function, enabling operation on a timed basis, helping to reduce return temperatures and providing flexibility over heat network configuration
• Weather compensation, which allows secondary system flow temperatures to be automatically adjusted based on outdoor temperatures
• Automatic control of pump speed to maintain delta T on secondary circuit, helping low return temperatures to be maintained

SmartTalk® Communications Network – Internet Connected

An additional benefit of using our electronically controlled heat interface units is that they can operate on a 2‐way communication network, which when connected over the internet to remote servers means the ModuSat HIU becomes an IoT device, offering a wide range of benefits to both consumers, facilities managers and heat network operators a like.
