Hydro Kit compatibility
The Hydro Kit is fully compatible with Multi V III, Multi V IV and Multi V Water IV units. The Hydro Kit is not compatible with Multi V Mini, Multi
V Plus II, Multi V Sync II, Multi V Space, Multi V Water II, Multi V Water Mini or any duct-free split products.
1
Hydro Kit models (i.e., K2 and K3 chassis) cannot be mixed within the same group. Each Hydro Kit unit group must be connected to the same outdoor unit.
Hydro Kit units within the same group must have the same DIP switch settings. The only DIP switch that can differ is the group control setting switch, where
one Hydro Kit will be the master and the remaining Hydro Kit units will be slaves.
2
Manual restart is not available when the Hydro Kit is configured for conditioned space control, using a conventional thermostat.
