High Temperature Hydro Module
202003 41
When the water system side of multiple hydraulic modules are connected in parallel and heat water for a single
water tank, you need to set master and slave hydraulic modules. The temperature sensor of the water tank is
connected to the master hydraulic module and the master hydraulic module sends the water tank temperature to
the slave hydraulic module.
Only the wired controller connected to the master unit can be used to set the desired water tank temperature.
The master unit is used to control the switch of the circulating water pump.
In all the preceding installation scenarios, it is recommended that the automatic air discharge valve should be
installed at the highest point of the water system.
