3 Installing temperature sensors 3.1 Outdoor temperature sensor The heat pump’s outdoor temperature sensor (B9) is delivered with the heat pump. See the necessary sensor connections in the unit’s electric diagram. ● In two-unit RE models, connect the sensor to controller A1.0 (master controller, in the upper unit).
● If a dedicated tank is used, install the sensor in the lower section of the tank. ● If a combined storage tank is used, install the sensor in the upper section of the tank. ● Install the sensor probe (supplied with the unit) into a sensor pocket designed for 6-mm probes.
The sensor cable is approximately 4.5 m long. The sensor probe’s diameter is 6 mm and length 50 mm. The cable can be extended if required. Use a regular insulated copper twin cable for connecting the cable and extending the cable (0.5 mm , length <...

If the pipe has a small diameter, create a 90 degree turn in the line flow direction with a tee fitting. Place the sensor pocket in the outlet that is parallel to the original line. The probe itself should extend upstream from the turn. This will allow you to install even a long sensor pocket (150–200 mm) along the line.
4 Commissioning 4.1 Configuring automation settings 1. Keep the operating switches in the OFF position. ● In RE 28–48 models, the operating switch is S1. ● In RE 56–96 models, the operating switches are S1 and S2 2. Keep the compressor motor protection circuit breaker (breakers) in the OFF position.
● Starting up too frequently may cause damage to the soft starter. 6. Make sure that the compressor rotates in the right direction, see the table below. ● If the compressor rotates in the wrong direction, stop the compressor immediately by moving its motor protection circuit breaker (RE 28–48: F1; RE 56–96: 1F1) to the OFF position or by turning its operating switch to the OFF position.

2355A06 ver. 1 RE 56–96 In standard two-unit RE heat pump deliveries, the units’ automation systems have been connected for joint use in a cascade. The cascade is controlled with a sensor (B10) installed in the cascade’s shared flow line. By default, the cascade system includes one shared brine pump and two condenser circuit pumps.

5.3 Start page From the start page, you can switch all heating circuits assigned to the relevant user interface ON or OFF in one go. When switched ON, all heating circuits will operate in automatic mode. When switched OFF, all heating circuits will operate in frost protection mode.
When using factory settings, the heating circuits have Automatic mode enabled, and the time program keeps Comfort mode on permanently. If a time program is used to switch from Comfort mode to Reduced mode, Comfort mode can be temporarily restored by selecting a temporary operating mode for the heater (from the Temporary setting).

6 Cascade connection 6.1 Cascade connection In a cascade connection, two or more heat pumps are connected to a system that is controlled by a single heat pump controller. One of the RVS61 heat pump controllers connected to the system operates as the master controller (which controls the entire system), and the other RVS61 controllers operate as slaves (which are controlled by the master controller).
Heat pumps in the cascade Master Slave Slave S0/G1 S0/G2 S0/G3 Line Line Line Master controller’s sensors, actuators, and S1 = Slave S0/G2 6600 = 1 6600 = 2 6600 = 3 functions S2 = Slave S0/G3 6.2 LPB bus configuration The system’s controllers are connected to an LPB bus (DB+/MB–).
Page 40
● Check the cables and if necessary, use cables with a greater wire cross- sectional area. ● If there is no voltage present, the bus has short-circuited. ● If the voltage is negative, the polarity is incorrect. Bus addresses Each device in the bus has its own address. Set the device address from the user interface itself (line 6600).
The segment ID and the device address constitute the controller’s entire address. The address can be, for example, S0/G1 or S0/G2, which means segment 0’s (S0) master (G1) and its first slave (G2). The ACS program can only be connected to device address 1 (the master controller). Any slave controllers connected to the bus will be displayed in the program through the master controller.
Connect the pump using the regular brine pump output (Q8) in any of the controllers connected to the cascade. ● Select the controller to which the shared pump is connected on line 5803. ● By default, the setting for the line is 1, which is the master controller’s device address.
7 Technical data 7.1 Technical data The performance between different units may vary. This variation is due to a wide number of factors, such as the properties of the fluids used in the circuits, fouling of the heat transfer surfaces in the condenser and evaporator circuit, flow rates, individual differences between compressors (standard EN 12900) as well as refrigerant circuit charge and adjustments made to the refrigerant circuit during installation.
