| AMBIENT TEMPERATURE CORRECTION |
|
The thermal output figures are based on an ambient temperature of 20OC and may be corrected for other ambient temperatures in the range of 0OC to 40OC by multiplying by the factor “R”.
TESTED TO BS EN 442-2: 1997 where R = T-Ta T = Mean temperature of heating medium °C. T-20 Ta = Ambient Temperature °C. |
