*1 The settings related to Zone2 can be switched only when Zone2 temperature control is enabled (when Dip SW2-6 and SW 2-7 are ON).
*2 Cooling mode settings are available for ERSC-VM2B only.
*3 Only available if DHW tank present in system.
*4 Decreasing “time before pump switched off” may increase the duration of stand-by in Heating mode.
