Page 17: Defrost System
DESCRIPTION OF THE DEFROST SYSTEM The defrost process is activated during heating mode in heat pump units, when the outside temperature is low and the outdoor coil could become frozen. To melt the ice the defrost function will switch the unit to cooling operation for a short period. During defrost mode the low pressure is at minimum level, consequently the pressostat is disabled in this mode. -
Page 18: Fan Speed Control
FAN SPEED CONTROL Fan speed control: Management of the fan speed. It is management by a fan speed control plate located at the electrical box of the unit The function of this fan speed control is allowing the unit to operate at very low outside temperatures from -10ºC to 46ºC during cooling mode. - Page 19 INSTALLATION-OPERATION & MAINTENANCE MANUAL x 1000 mode on off CONTROLLER E210 / E420...
