Swegon heat pump
A pump and accumulator tank
can be added and, depending
on the size of the system, can
be located inside or outside the
heat pump.
The external air heater can be
of water-coil or electric type.
3.5 Heat pump and external heating
The heating capacity of the supply air is controlled via an
IQlogic
+
module (extra regulation sequence function, see
separate instructions for the TBIQ IQlogic
+
module) preset
for heating (0-10 V). The function can be activated in the
hand-held terminal of the GOLD air handling unit (see the
Operation and Maintenance Instructions for the GOLD).
The function controls external heating (waterborne or
electric) via the GOLD unit’s ordinary output for heat-
ing (0-10 V). The air heater for heated water has a frost
monitor function and is automatically activated when it is
connected.
Communication with the heat pump can be activated
under Functions in the hand-held micro terminal of the
GOLD unit. See Section 5.
If temperature sensor BT1 calls for heating, the function
transmits a start signal and heating medium setpoint
(40°C*) to the heat pump via Modbus.
If the temperature by temperature sensor BT50 is higher
than the temperature by temperature sensor BT30**, the
function allows valve MF1 to regulate the flow.
If the temperature by temperature sensor BT50 is lower
than the temperature by temperature sensor BT30**, the
function does not allow valve MF1 to regulate the flow
(forces it to close).
Optimisation function active:
To ensure the best functionality when the optimisation
function is activated, the heating diff. value (3 K*) should
be set to the same value as that set in the heat pump. See
Section 5.
If the temperature by temperature sensor BT40 (reference
water) is within 3K* from the heating medium tempera-
ture setpoint and if it has been so during a continuous
period of more than 60 seconds* the optimisation func-
tion is allowed.
If the optimisation function is allowed and valve MF1 is
fully open (100%*) the controller increases the heating
medium temperature setpoint at a rate of 0.3K/minute*.
If the optimisation function is allowed and valve MF1 is
open less than 80%*, the controller decreases the heating
medium temperature setpoint at a rate of 0.6K/minute*.
* Factory setting. The value can be changed.
