Features:
*TPI or Time Proportional + Integral Control is a method of calculating the demand from a room thermostat, controlling the boiler so that it fires for shorter periods as the temperature approaches the set point. This is an industry standard term, describing a mathematical calculation of demand.
TPI allows the flow temperature from the boiler to fall as demend reduces, which, in turn, helps the return termperature to stay below the Dew Point (55oC) so that the boiler can operate in condensing mode more frequently. This effect is referred to as Load Compensation and currently accrues a 3% boiler efficiency increase under the SAP calculations.
Benefits:
Wireless controls are quicker and cleaner to fit. There are numerous extra benefits over a wired approach:
The adaptable nature of wireless allows for the user to control their heating requirements, rather than being restricted by what was originally fitted. For example, wireless zoning and wireless radiator valve controllers make use of wireless signals and once installed can be moved to alter how the system performs, with the minimum of fuss.
By locating the receiver in the right place, a system can be made exempt for Part P notification.
Fault finding is easy, as signals can be induced within the home and made to operate the correct devices without reference to previous work.
Robust RF protocols ensure that signals are sent, received and acted upon reliably, with no confusion of signals, resulting in improved control efficiency and increased confidence in systems acceptability.
Two way wireless communication also gives better feedback on installation and during use. Signal strength is displayed on screen and the binding is confirmed at both the sending and receiving devices.
