Examples of water circuitation:

4.1.2 External heat source

4.1.3 Dehumidier or a Humidier

An External Heat Source can be driven by Aquasnap Plus.

For this feature is necessary install 33AW-CS1 interface

Procedure to install an External Heat Source

Connect electrically EHS to N and 4 terminals to a relay that drives 1.

EHS

Congure parameter 106 through 33AW-CS1 interface (1 for EHS)2.

Congure outdoor temperature limits (parameter 148 and 150). 3.

A Dehumidier or a Humidier can be driven by Aquasnap

Plus using humidity sensor into 33AW-CS1 interface.

For this feature is necessary install 33AW-CS1 interface

Connect electrically a Dehumidier or a Humidier to 1.

N, 11 terminals to a relay that drives Dehumidier (NO

contact) or a Humidier (NC contact)

Congure parameter 108 through 33AW-CS1. (2 for 2.

dehumidier /Humid.)

Congure ambient humidity limit (parameter 107) 3.

OAT < -2°C + hysteresis)

To change the delta T needed to activate the EHS change the 4.

parameter 152. (Factory default 5 °C).
