McQuay , like the IV/AC ler for water source heat pump s, are very popular. The IV/AC ler provides features which improve the operation and safety of AAF-McQuay heat pumps. Some features provided are protection from the compressor shorting, protection from condensate overflow, protection from refrigerant extreme pressure variation, protection from low temperature, protection from low voltage conditions, brownout protection, fault indicators, and remote shutdown , among other protective features. The IV can also be interfaced to external equipments

The multiple is an accessory used when you need to more than 1 from a single . The multiple provides the components required to protect the IV/AC from electrical damage that may occur when using standard off-the-shelf relays. The Multiple Panel or MUCP for use with MicroTech III ler and IV ler is optionally used when there is a need to connect up to 3 s from a single .

The IV/AC ler incorporates features which improve the operation and safety of AAF-McQuay heat pumps.

The IV/AC is provided with three drive terminals, R (24vac), F (24vdc), and C (0vac) that can be used by the end user to drive the inputs (G, Y1, W1, and W2) and inputs (U, L, E, and O). Any combination of or single drive terminal (R, F, or C) may be used to operate the IV/AC s or inputs. However, only one drive terminal (R, F, or C) can be connected to any individual input terminal or damage will occur.

Typically the IV/AC ’s R (24vac) terminal is used to drive the ’s inputs and inputs by connecting it to the R terminal of an industry standard . The outputs of the standard are then connected to the IV/AC inputs and inputs as needed. Any remaining input(s) may be operated by additional outputs or remote relays (dry contacts only). All IV/AC inputs must be operated by dry contacts powered by the ’s power terminals. No solid state devices (Triacs) may be used to operate IV/AC inputs. No outside power sources may be used to operate IV/AC inputs.

Multiple Panel (MUCP) for Use With MicroTech® III ler and IV ler

The Multiple Panel (MUCP) is an accessory used when up to 3-s are led from a single . It is typically mounted in the box closest to the . A maximum of 2 s may be used together if up to 6-s must be connected and led from a single .

The multiple provides the components necessary to protect the MicroTech III ler and the IV ler from electrical damage that may occur when using standard off-the-shelf relays.
