Mergen M4512 Tech Specs

Control Modes

The MERGEN unit has a factory-programmable regulator as standard used to configure the flow modulations described below:

Mode 1	Standad Control (Supply Air Temperature Control with outdoor compensation, %Low Speed – %High Speed – Time Based LS/HS Speed Shift)
Mode 2	CO2 Control (Supply Air Temperature Control with outdoor compensation, %Low Speed – %High Speed – CO2 Concentration Based LS/HS Speed Shift)
Mode 3	Supply Duct Constant Pressure Control (Supply Air Temperature Control with outdoor compensation, %Low Speed – %High Speed – Supply Duct DP Based LS/HS Speed Shift)
Mode 4	Constant Flow Control (Supply Air Temperature Control with outdoor compensation, Constant Low Speed in m3/h – Constant High Speed in m3/h – Time Based LS/HS Speed Shift)
Mode 5	Constant Flow CO2 Control (Supply Air Temperature Control with outdoor compensation, Constant Low Speed in m3/h – Constant High Speed in m3/h – CO2 Concentration Based LS/HS Speed Shift)
