MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 Description HC-003-43 is a versatile control module for use in MULTICAL® 403, MULTICAL® 603 and MULTICAL® 803 energy meters. The PQT Controller is for applications to optimize energy consumption. The PQT Controller works together with the MULTICAL® energy meter and reads the meter’s flow, power, temperature difference and outlet temperature. The read data is used together with the limit values configured in the module to control the connected motor valve. The controller is fully programmable and can be selected to regulate according to one or more...

MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 Cable connections Terminals Max cable size 1.5 mm² Motor Terminal 150: Motor Up Terminal 151: Motor Com Terminal 152: Motor Dn Test Short circuit to open Short circuit to close External power Terminal 98: 24 VAC Terminal 97: 24 VAC Connection diagram When the power supply and motor valve are connected, you can test whether the valve opens and closes correctly by short-circuiting the Test-Up and Test-Dn solder pads, e.g. by using a small screwdriver. If the valve runs in the opposite direction, the supply cables Dn Y2 and Up Y1 must be exchanged.

MULTICAL® 403 MULTICAL® 603 MULTICAL® 803 Mode of operation PQT Controller is designed with more set-points and gain-factors. One part controls power and flow (PQ control), another part controls the outlet temperature and differential temperature (t2∆t control). The control will always adjust towards the most restrictive limit, whether it is flow, power, t2 or ∆t. PQ control Flow set‐point Power set‐point PQ control The control of power and flow takes place in the same part of the controller as the power is calculated on the basis of flow. For the PQ control to be active, one or both...
