HIGH-TEMPERATURE AIR-TO-WATER HEAT PUMPS
61AF 014-019
Hydronic module (option)
The hydronic module option reduces the installation time.
The heat pump is factory-equipped with the main hydronic
components required for the installation: screen filter, water
pump, relief valve, water pressure transducer, flow
switch.
However, for applications with two-way valves a bypass
system must be kept to guarantee the minimum flow rate.
Pro-Dialog+ includes two operating modes:
- Constant pump speed
- Constant delta T control.
The Pro-Dialog+ control allows integration of system and
water pump protection devices (insufficient water flow rate).
An automatic pump start-up algorithm protects the heat
exchanger and the hydronic module piping against frost
down to -20 °C.
The pump supplied with the hydronic module is a variablec
speed pump. With variable speed flow, the system no longer
requires the control valve at the unit outlet.
The hydronic module option is integrated into the heat pump
without increasing its dimensions and saves the space
normally used for the water pump.
