3.5.5 PC-AMTB
PC-AMTB is a connection board for multitenant buildings (ofîš¿ce buildings, multi dwelling, small hotels). It provides a solu-
tion in such installations with a refrigerant system compounded by several indoor units of different tenants with a common
shared outdoor unit (typically Set Free systems), when the power supply of some indoor units is shut-down together with
the tenant installation without causing refrigerant systems problems.

This device keeps the presence of the indoor unit in the refrigerant system control, even if the relevant indoor unit is discon-
nected, and it manages the expansion valve control in order to adjust the refrigerant ow accordingly.
PC-AMTB is power supplied at 24 VDC or VAC from a power net independent from the tenant installation.
3.5.6 THM-R2AE
The THM-R2AE is a remote sensor for the indoor units used to control the indoor temperature by an average air tempera-
ture between the indoor inlet and the remote sensor point. The cord of the remote sensor must be connected to THM4
connector in the indoor unit. This cord has a length of 8 m, but using an extension cord (îš¿eld-supplied, with wire size over
0.3 mm
2
) it can be extended up to 15 m (including the extension cord length).
