temperature control Parameter setting for Hydro Kit Medium temperature
The following Function Codes are used to set weather-dependent
operations. Refer to Figure 59 for an example of this function.
function Codes 22 - Setting Cut-off Temperature in
Cooling Mode (fCU Setting Included)
Determine leaving water temperature when the unit is turned off.
This function code is used to prevent condensation on the floor while
Hydro Kit is in cooling mode.
• Value #1: Cut-Off Temperature. Value #1 is read by the unit when
Value #2 is set to '00' (i.e., FCU is installed).
• Value #2: FCU Installed/not installed.
'00' = FCU Installed;
'01'= FCU Not Installed.
fcu Installation
• If FCU is used, 2-way isolation valve is installed and connected to
the Main PCB Assembly 1.
• If Value #2 is set to '00-, and FCU or 2-way isolation valve is Not
installed; unit will not operate correctly.
function Codes 23, 24, and 25 - Setting Weather-dependent
operation
The unit will automatically adjust target temperature (leaving water
or room air) based on outdoor air temperature.
• Value #1 and Value #2 of Function Code 23: Range of outdoor air
temperature.
• Value #1 and Value #2 of Function Code 24: Range of indoor room
air temperature.
• Value #1 and Value #2 of Function Code 25: Range of auto-adjust-
able target leaving water temperature.
