RADIANT PANEL SYSTEM CONTROL QUICK GUIDE

2015

Terms and definitions

The system temperature regulation can be carried out in only two basic ways:

1 Flow rate control of the medium feeding the heat exchanger terminals at a constant temperature. Thisapproach uses ON/OFF valves or flow modulating valves, with the pump always upstream of the valve.

2 Flow temperature control of the medium feeding the terminals at constant flow rate. Thisapproach employs modulating mixing valves to control the temperature and the pump is alwaysdownstream of the valve.

Panel system temperature regulator units control the temperature of the medium supplied to thepanels according to method (2). The flow temperature to the panels is generally different from thatof the boiler or chiller unit, so that there must be a mixing unit upstream of the circulation pump forthe panels circuit.

We give below a number of definitions used in the temperature regulation by means of regulationunits.

The flow temperature supplied tothe system varies depending on the outside temperature changesaccording to a regulation curve.

The flow temperature supplied tothe system varies depending on thereturn temperature changes fromthe system. This latter temperature is thecharacteristic parameter of theactual instantaneous thermal load.

The flow temperature supplied tothe system is constant at anadjustable value.

Electronic device which processesthe temperature signals, using amicroprocessor and software, andsends control signals to theregulation valve actuators.

Mechanical device working bymeans of a thermostatic elementexpansion or contraction in contactwith the fluid being controlled.

Simultaneous control of the primarycircuit medium and the systemreturn medium. They are mixeddirectly inside the valve.

Simultaneous control of the primarycircuit medium and the systemreturn medium. They are mixeddirectly inside the valve, so as toenable double circulation on boththe primary and secondary circuit.

Electrically supplied actuator withcommon contact, opening contactand closing contact. The contactsare supplied directly by the regulator,which is also a three-point type.

Mechanical device controlled by abuilt-in sensor containing thethermostatic element which expandsor contracts.
