Note: where a PCDB record for a Compensating boiler control and/or Time & Temperature Zone Control (TTZC) identifies that a boiler is compatible, this is not guaranteed and should not be relied upon for product selection. Manufacturer advice should always be sought. SAP assessors must ensure that the Compensating boiler controls and/or Time & Temperature Zone Control (TTZC) is fitted to the dwelling if specified in the SAP assessment. If it is not installed the PCDB record does not apply and must not be selected by the SAP assessor.
