Bifunctional meters When the cooling energy tariff function is activated, in case of a negative temperature differential,
energy will be accumulated in the additional tariff register Q . In this case, energy values are
calculated according to the following formulas:
– when the flow sensor is in the supply line
when Θ1 > Θ2: Q = V · ρ1 · (hΤ1-hΤ2), Q  = 0
when Θ1 < Θ2: Q  = V · ρ1 · (hΤ2-hΤ1), Q = 0
– when the flow sensor is in the return line
when Θ1 > Θ2: Q = V · ρ2 · (hΤ1-hΤ2), Q  = 0
when Θ1 < Θ2: Q  = V · ρ2 · (hΤ2-hΤ1), Q = 0
