ModuSat® XR Combined Heating, Domestic Hot Water and Cooling (CHHC) interface Units

The perfect solution for apartments where both cooling and heating are required, ModuSat® XR CHHC units are designed to deliver both heating and cooling and the instantaneous production of hot water.

Smart Energy Regulation and Control

Our Smart Energy Regulation and Control provides a myriad of benefits in terms of HIU performance and optimisation of heat network efficiency. So how does it work?

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

Metering and Billing Ready

The Heat Network (Metering & Billing) Regulations (2014) require each resident to be billed individually for the proportion of the total heat they consume from the heat network.

Our ModuSat® units make this easy, featuring an integrated ultrasonic heat meter, which is MID approved with class 2 accuracy (BS EN 1434), ready to connect to a communication network for metering and billing purposes.

In addition, our PaySmart® pre-payment technology is also integrated into each ModuSat® heat interface unit as standard, and – unlike many other pre-payment billing solutions – can easily be activated remotely at any time and requires no additional hardware or infrastructure to set up.

Technical details

ModuSat® XR Combined Heating, Domestic Hot Water and Cooling Interface

The ModuSat® combined heating and cooling unit provides heating, cooling and the instantaneous production of hot water. Designed to simplify apartment installations where cooling and heating is required; the CHHC unit features a small footprint that minimises required cupboard space, with easy access for service and maintenance.

The heating, domestic hot water and cooling plate heat exchangers are housed within a single cased unit with high quality fully insulated separation between the hot and chilled zones. The unit can be provided in either floor standing or wall mounted orientations making them suitable for a wide range of installation configurations.

Heating

The heating circuit consists of a plate heat exchanger (PHE), safety relief valve, manometer, flow and return temperature sensors, Wilo PWM circulation pump and expansion vessel. The heating circuit flow temperature is controlled by the modulation of the primary flow rate with the integrated PICV actuator. Weather compensation is applied to the set heating temperature using SmartTalk® 2-way communication. Suitable for radiators, underfloor heating or fan coil units.

Domestic Hot Water

Domestic hot water is heated via a separate plate heat exchanger and the temperature is regulated by the modulation of primary flow rate with the integrated PICV actuator.

Cooling

The Cooling circuit consists of a plate heat exchanger (PHE), safety relief valve, manometer, flow and return temperature sensors, Wilo PWM circulation pump and expansion vessel. The cooling circuit flow temperature is controlled by the modulation of the primary flow rate with the integrated PICV actuator.

The ModuSat® CHHC is available with a number of plate size options to meet a range of cooling, heating and DHW requirements and is supplied complete with a ViewSmart room controller.
